Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display panel which is excellent in display quality capable of maintaining a more uniform cell pitch. [Prior Art] Since the liquid crystal display panel has excellent characteristics such as thinness, light weight, and low power consumption, it is used in displays for various information devices including computer monitors and television monitors.

In the operation mode of the liquid crystal, there are various modes, and a twisted nematic (TN) mode and a super twisted nematic (super Twisted Nematic) are known in which a longitudinal electric field is applied between the substrates to control the molecular arrangement of the liquid crystals. STN) In the case of the substrate, the molecular arrangement of the liquid crystal is controlled by the electric field in the horizontal direction to obtain an In-Plane Switching (IPS) mode of a wide viewing angle. The liquid crystal display panel of any operation mode electrically controls the molecular arrangement of the liquid crystal by the array substrate, and selectively changes the amount of backlight light transmitted through the color filter substrate for display. Conventionally, the cell pitch between the array substrate and the color filter substrate is often such that spherical particles called spacers made of plastic or the like are dispersed and maintained between the two substrates. The particle size of the material is an important factor in forming the cell pitch, and the dispersion accuracy is also required. However, it is difficult to uniformly control the scattering density of the spherical spacers in the plane of the substrate, and the spacers which are uneven in the pixels are scattered/interrupted to reduce the light from the backlight, etc., and the like. The display quality of the liquid crystal display panel is such a problem. Therefore, in recent years, as shown in Fig. 1, columnar column spacers 1 16 are used instead of spherical spacers. The liquid crystal display panel 1 10 in FIG. 1 includes: an array substrate 1 1 2, a color filter substrate 1 1 4 facing the surface of the array substrate 1 1 2 with a cell pitch, and a pattern for holding the array a plurality of column spacers 116° between the substrate 1 1 2 and the color filter substrate 1 1 4

The edges of the two substrates 1 1 2, 1 1 4 are fixedly sealed. Further, a black matrix 124 for light that blocks a boundary portion between pixels is formed in the color filter substrate 1 14 . Further, an alignment film 118 is formed on the surface of the array substrate 112, the color filter substrate 114, and the column spacer 116, and the polarizing plate 122 is disposed in contact with the liquid crystal 1 2 0 of the two substrates 112 and 112. On the side. Moreover, the cell pitch adjustment method is as described above except that between the two substrates 112 and 114, that is, a spherical spacer or a columnar spacer 1 16 is applied with a pressure sealing load to adjust the cell spacing of the liquid crystal. In addition to the injection method, there has been a drip injection method (hereinafter referred to as 0DF (0ne Drop Fill) method) which has been put into practical use in recent years. In the ODF method, the pressure seal load is not applied to the column spacer 116, and the cell pitch between the two substrates 1 1 2 and 1 14 is adjusted by the amount of liquid crystal. The liquid crystal injection method is used for both liquid crystal display panels composed of spherical spacers and serpentine spacers 1 1 6 , and the ODF method is used exclusively for 枉

As a result, when the display panel 110 is placed in a vertical state, the pressure distribution of the liquid crystal 120 in the fifth (b) diagram occurs in the liquid crystal display panel 1 10 depending on the gravity acting on the liquid crystal 120.

型電視顯示器的液晶顯示面板的大型化正加速中。因為這種 大型電視顯示器用的液晶顯示面板通常係垂直豎起於地表 的狀態下來使用，所以會存在由重力所造成之液晶的壓力分 布。因此，特別是在大型液晶顯示面板中，因為在面板内發 生的内壓分布，而會在上部與下部發生晶胞間距的差。而且 ，有時也會因來自背光的熱而使液晶顯示面板升溫到50°c以 上7 0 °C左右的高溫。在如此實際使用環境下的液晶顯示面板 中，因為將面板垂直豎起來使用，所以具有容易發生因晶胞 間距的差而造成的顯示不均·勻，顯著的例子為特別是在高溫 化中所發生的重力不均勻。 在此所謂的重力不均勻係指在豎起液晶顯示面板的狀 癌下以向溫保持時*在液晶的熱膨服超過柱狀間隔物於液晶 密封時之彈性變形量範圍之場合時，液晶胞内的液晶因重力 作用而積存於下部，而被認定為間距不均勻的現象。第9(a) ~(c)圖係圖示在進行利用加壓密封的液晶密封的場合時發生 重力不均勻的機構。 第9(a)圖係顯示在常溫施加加壓密封荷重至兩基板，亦 即柱狀間隔物116，以密封材黏著兩基板的兩端而密封液晶 120的液晶顯示面板110。在此狀態下各柱狀間隔物116因 加壓密封荷重而彈性變形。其次，若對加壓密封液晶1 2 0的 液晶顯示面板1 1 0加熱，則液晶1 2 0熱膨脹，晶胞間距增加 ，柱狀間隔物1 1 6的彈性變形減少》若柱狀間隔物1 1 6的伸 長無法隨著晶胞間距的增加而進行，則如第9(b) I所示會變 成因液晶的熱膨脹而使陣列基板1 1 2或彩色濾光片基板1 1 4 -10-The size of the liquid crystal display panel of the TV display is accelerating. Since the liquid crystal display panel for such a large-sized television display is usually used vertically in the state of being erected on the ground surface, there is a pressure distribution of the liquid crystal caused by gravity. Therefore, particularly in a large liquid crystal display panel, the difference in cell pitch occurs in the upper portion and the lower portion due to the internal pressure distribution occurring in the panel. Further, the liquid crystal display panel may be heated to a temperature of about 50 ° C or higher at a temperature of about 70 ° C due to heat from the backlight. In the liquid crystal display panel in such a practical use environment, since the panel is vertically used upright, display unevenness and uniformity due to a difference in cell pitch are likely to occur, and a remarkable example is particularly high temperature. The gravity that occurs is not uniform. The term "gravity unevenness" as used herein refers to a case where the temperature of the liquid crystal display panel is maintained at a temperature of * when the thermal expansion of the liquid crystal exceeds the range of the elastic deformation amount of the column spacer at the time of liquid crystal sealing, the liquid crystal The intracellular liquid crystal accumulates in the lower portion due to gravity, and is considered to be a phenomenon in which the pitch is uneven. Figs. 9(a) to 9(c) are diagrams showing a mechanism in which gravity unevenness occurs when a liquid crystal sealing by pressure sealing is performed. Fig. 9(a) shows a liquid crystal display panel 110 in which a liquid crystal 120 is sealed by applying a pressure seal load to a substrate at a normal temperature, i.e., a column spacer 116, with a sealing material adhered to both ends of both substrates. In this state, each of the columnar spacers 116 is elastically deformed by the pressure seal load. Next, when the liquid crystal display panel 1 10 that pressurizes and seals the liquid crystal 120 is heated, the liquid crystal 1 2 0 thermally expands, the cell pitch increases, and the elastic deformation of the column spacer 1 16 is reduced, if the column spacer 1 The elongation of 16 cannot be increased as the cell pitch increases, and as shown in Fig. 9(b) I, the array substrate 1 1 2 or the color filter substrate 1 1 4 -10- may be caused by thermal expansion of the liquid crystal.

When the crystal display panel 1 10 of FIG. 9( b ) is vertically held to the ground, the liquid crystal 1 2 0 is accumulated in the lower portion of the liquid crystal display panel 110 due to gravity, and gravity unevenness occurs. . In the seventh (a) diagram, a pressurized sealing load is applied between the two substrates of the liquid crystal display panel 1 1 〇 used as described above, that is, a pressure sealing load is applied to the two spherical spacers and the pressure is sealed. A cross-sectional view of the panel 110 when it is erected. Unlike the fifth (a) diagram, the liquid crystal display panel 110 shown in Fig. 7(a) is very large so that the internal pressure as shown in Fig. 7(b) is large (P = I y). = yatm (-h/2Syatm$h/2), which is different. In the liquid crystal display panel 110, the above-described mechanism 1 2 0 is accumulated in the lower portion of the liquid crystal display panel 110, and is in the yatm S: region. In the middle, the internal pressure of the liquid crystal 120 is better than the external pressure (=atmospheric pressure), and the cell pitch distribution is as shown in Fig. 8. In the eighth figure, the horizontal L = 0 mm and the right end L = 20 mm correspond to the seventh (b) figure, respectively. And the cell spacing y = h / 2 fixed by the sealant 126. Moreover, the vertical axis indicates the natural long cell spacing from the column spacer 1 16 , 0.6t, 0.7t, and l.lt It is shown that the glass thickness of the color filter substrate 1 14 is 0.6 mm, 0-7 mm, respectively. It is obvious from Fig. 8 that the thinner the cell pitch is, the larger the amount of change in the cell pitch is. A method for displaying display unevenness caused by a difference in cell pitch is disclosed in Document 1. The liquid crystal display module disclosed in Patent Document 1 relates to a liquid in a differential state. In the 9th (c) part, the difference in the liquid crystal between the display boards of the display is the same. If the liquid crystal y S h/2 in > atm = 1 atm), the origin of the axis is y = yatm In the case of the change amount of 1 · 1 mm in Fig. 8, the glass is not easily disclosed in the patent L.

In the case of the above, the spacer is maintained in a state of being elastically deformed in accordance with the pressure from the substrate.

In the following description, y is the ordinate of the gravity direction in the case of vertically erecting the liquid crystal display panel, which satisfies - h/2 $ y $ h/2 . That is, the y coordinate of the upper end of the display area of the liquid crystal display panel is y = -h/2, and the y coordinate of the lower end of the display area is y = h/2. Further, the internal pressure caused by the gravity of the liquid crystal acting on the liquid crystal display panel is P, Patm = latm, the y coordinate of P = Patm is y = yatm 〇 (1), and the internal pressure P is atmospheric pressure (P = Patm y = yatm (-h/2 $ yatm S h/2) does not exist in the liquid crystal display panel. That is, the internal pressure P is often under atmospheric pressure.

Hereinafter, embodiments of the liquid crystal display panels of the present invention will be described with respect to the above (1) and (2). (1) For the absence of internal pressure P is atmospheric pressure (P = Patm) -16 - 1322315 (-50mm ^ 50mm) Therefore, at the upper end of the measurement range of the cell pitch (y = - 50 mm) and the lower end η (y = 50 mm) yields a difference in cell pitch of 0.13; zm.

However, the lower portion of the liquid crystal display panel 110, that is, y is larger, the elastic deformation Ad(y) of the columnar spacer 116 is smaller than 1322315. In other words, the columnar spacer 1 16 is extended to the lower portion of the liquid crystal display panel 1 10 ( y is large, and is closer to the natural length and becomes higher. Therefore, as in Mathematical Formula 2 derived from the measurement data, it is considered that the closer to the lower portion (y is larger) of the liquid crystal display panel 110, the larger the cell pitch. Therefore, in order to make the deformation amount Δ d (y) of the columnar spacer 1 16 uniform, that is, the distribution of the cell pitch, it is necessary to make A d (y) a predetermined constant Δ d 〇 » Therefore, the liquid crystal display panel of the present invention It is necessary to have the elastic coefficient distribution k(y) expressed by the following mathematical formula 4.

Where kps (y) is the elastic modulus of a column spacer 1 16 such that a(y) is the occupation ratio of the column spacer 116 per unit area of the liquid crystal display panel 110, then the general elastic coefficient distribution k ( y) can be written as follows.

液晶顯示面板1 〇被隔牆3 0 a、3 0 b分離成三個晶胞5 0 a 、50b、50c，下方的晶胞内的液晶 20藉由隔牆不會受到上 方的晶胞内的液晶2 0所造成的重力的影響。即晶胞5 0 b内 的液晶20藉由隔牆30a而由來自晶胞50a内的液晶20的内 部壓力釋放，晶胞50c内的液晶20藉由隔牆30b而由來自 晶胞50b内的液晶20的内部壓力釋放。 因此，各晶胞 50a、50b、50c内的内部壓力如第 圖所示，變成各晶胞内的液晶20的内部壓力的分布，可宛 如獨立的液晶顯示面板般來處理。即在第l(b)圖中各晶胞内 的内部壓力與表示單一的液晶顯示面板的内部壓力的數學 式1 一樣，可如下式數學式6而書寫。 [數學式6] P(y) = P〇-( 1/2) p gha+p gy (0^ y ^ ha) P(y) = P〇-(1/2) p ghb+p g(y-ha) (ha‘ yS ha + hb) -22-The liquid crystal display panel 1 is separated into three cells 50a, 50b, 50c by the partition walls 30a, 30b, and the liquid crystal 20 in the lower unit cell is not subjected to the upper cell by the partition wall. The effect of gravity caused by liquid crystal 20 . That is, the liquid crystal 20 in the cell 50b is released by the internal pressure from the liquid crystal 20 in the cell 50a by the partition wall 30a, and the liquid crystal 20 in the cell 50c is derived from the cell 50b by the partition 30b. The internal pressure of the liquid crystal 20 is released. Therefore, the internal pressure in each of the cells 50a, 50b, and 50c becomes a distribution of the internal pressure of the liquid crystal 20 in each unit cell as shown in the figure, and can be handled like an independent liquid crystal display panel. That is, the internal pressure in each unit cell in Fig. 1(b) is the same as Mathematical Formula 1 indicating the internal pressure of a single liquid crystal display panel, and can be written in the following Equation 6. [Math 6] P(y) = P〇-( 1/2) p gha+p gy (0^ y ^ ha) P(y) = P〇-(1/2) p ghb+pg(y- Ha) (ha' yS ha + hb) -22-

Further, the upper unit cell is made to have a longitudinal length smaller than that of the lower portion haShbShc. Therefore, ΔPaSAPbSZ\Pc. This is! The partition wall with the b unit cell or between the b unit cell and the c unit cell is smaller than the average internal pressure, and the movement of the liquid crystal from the unit cell toward the b cell toward the c unit cell can be easily avoided. Therefore, since the pressure distribution of each unit cell is made wider than that in the large unit cell as described in the display of the first embodiment, the elastic system type 4 per unit area of the columnar spacer 16 can be adjusted. The liquid of the present invention having a uniform cell pitch is obtained. Hereinafter, the cell pitch liquid crystal display panel of the present invention will be described in more detail using an embodiment. [Embodiment 1] As described in the first embodiment of the present invention, in order to wide Δ Pa and Δ Pb atmospheric pressure, the unit cell is short*, which can make the pressure cell of the partition wall of the unit cell or b The crystal pressure is such that the fractional k (y) of each elastic coefficient satisfies the number of crystal display panels. It has a uniform crystal, and the cell pitch of the liquid crystal display surface -23-1322315 is uniform. If the elastic coefficient k (y) per unit area of the column spacer 1 16 satisfies the mathematical formula 4, the elastic coefficient k ( y) is expressed as follows. [Math 5] k(y)=kps(y) · a(y) k(y): elastic coefficient per unit area of columnar spacers k p s (y): —elastic coefficient of a columnar spacer
a(y):液晶顯示面板的每單位面積的柱狀間隔物的佔有率 在本實施例中令各柱狀間隔物的彈性係數 kps(y) = kps 為一定，使液晶顯示面板的每單位面積的柱狀間隔物的佔有 率a(y)依存於y而變化。其結果，a(y)應滿足的公式係令所 希望的晶胞間距的變化量為△<!〇，如以下而表示。 [數學式7] a(y) = (Patm-(P〇+P · g · y))/(A do · kps) △ d〇:液晶顯示面板由平行於地表轉為垂直豎起於地表之 際的晶胞間距之變化量（m) 再者，每單位面積的柱狀間隔物的佔有率a(y)係令柱狀 間隔物1 16的面積s為一定，使用柱狀間隔物的密度b(y)， 如以下而表示。 [數學式8] a(y)=s . b(y) b (y):柱狀間隔物的密度 s : —個柱狀間隔物的面積 因此，在本實施例一中使柱狀間隔物的密度b (y)滿足下 -24- 1322315 式數學式9，可得到均勻的晶胞間距的變形量為△ d〇的液晶 顯示面板。 [數學式9] b (y) = ( p a t m - (P 〇 +/0 · g · y)) / ( △ d 〇 · s · k p s) (-h/2 ^ y ^ h/2)a(y): the occupation ratio of the columnar spacer per unit area of the liquid crystal display panel is such that the elastic coefficient kps(y) = kps of each column spacer is constant in this embodiment, so that each unit of the liquid crystal display panel The occupancy rate a(y) of the columnar spacer of the area varies depending on y. As a result, the formula that a(y) should satisfy is such that the amount of change in the desired cell pitch is Δ <!〇, as shown below. [Math 7] a(y) = (Patm-(P〇+P · g · y))/(A do · kps) △ d〇: The liquid crystal display panel is turned from parallel to the surface to the vertical. The amount of change in the cell pitch (m), the occupancy rate a (y) of the column spacer per unit area is such that the area s of the column spacers 1 16 is constant, and the density of the column spacers is used. b(y), as shown below. [Math 8] a(y)=s . b(y) b (y): density of columnar spacers s: area of one column spacer Therefore, column spacers are provided in the first embodiment The density b (y) satisfies the following formula -24 - 1322315 Equation 9, and a liquid crystal display panel having a uniform cell pitch with a deformation amount of Δ d 可 can be obtained. [Math 9] b (y) = ( p a t m - (P 〇 + /0 · g · y)) / ( △ d 〇 · s · k p s) (-h/2 ^ y ^ h/2)
此外在本說明書中雖然柱狀間隔物1 1 6的面積s係以其 上底的面積，惟柱狀間隔物1 1 6的側壁部如第1 1圖未被蝕 刻（etching)成直線的形，如第 10圖所示通常係形成歪斜的 形狀"因此，柱狀間隔物116的上底的尺寸使用第10圖如 以下定義較佳（參照專利文獻 2)。首先，在柱狀間隔物 11 6 的上底210畫切線212,接著令與切線212同方向的下底214 的一邊的長度為D。其次，令柱狀間隔物116的下底214與 上底210的切線212的間隔為Η，令此高度Η乘未滿1的常 數C例如0.9的尺寸為距基板220的上底的高度（CxH)，在 其位置畫與基板220平行的線X，定義此線X與柱狀間隔物 1 1 6的側面2 1 8的交點間的間隔為上底的尺寸。因此，柱狀 間隔物116的每一個的面積s係定義為上述上底的尺寸所定 義的面的面積。 [實施例二] 其次，在本實施例二中令上述柱狀間隔物11 6的密度b 為一定，設每單位面積的柱狀間隔物116的佔有率a(y)的位 置依存性係起因於柱狀間隔物116的面積s(y)。 [數學式10] a(y)=s(y) · b -25- 1322315 b :柱狀間隔物的密度 s ( y): —個柱狀間隔物的面積 ·»* 因此，在本實施例二中使柱狀間隔物 1 1 6的面積 s (y) 滿足下式數學式1 1而變化，可得到均勻的晶胞間距的變形 量△ d〇的液晶顯示面板。 [數學式1 1] s(y) = (Patm-(P〇+/〇 · g* y))/(Ad〇· b- kps) (-h/2 ^ y ^ h/2)Further, in the present specification, although the area s of the columnar spacers 1 16 is the area of the upper base, the side wall portions of the columnar spacers 1 16 are not etched into a straight line as in FIG. As shown in Fig. 10, a skewed shape is generally formed. Therefore, the size of the upper base of the columnar spacer 116 is preferably defined as follows using Fig. 10 (refer to Patent Document 2). First, a tangent line 212 is drawn on the upper base 210 of the columnar spacer 11 6 , and then the length of one side of the lower base 214 in the same direction as the tangent line 212 is D. Next, the interval between the lower base 214 of the column spacer 116 and the tangent 212 of the upper base 210 is Η, and the height C is multiplied by a constant C of less than 1, for example, the size of 0.9 is the height from the upper base of the substrate 220 (CxH). The line X parallel to the substrate 220 is drawn at its position, and the interval between the intersection of the line X and the side surface 2 1 8 of the column spacer 1 16 is defined as the size of the upper base. Therefore, the area s of each of the column spacers 116 is defined as the area of the face defined by the size of the above-mentioned upper base. [Second Embodiment] Next, in the second embodiment, the density b of the columnar spacers 11 is constant, and the positional dependence of the occupancy ratio a(y) of the columnar spacers 116 per unit area is determined. The area s (y) of the column spacer 116. [Math. 10] a(y)=s(y) · b -25- 1322315 b : density s (y) of columnar spacer: - area of one column spacer ·»* Therefore, in this embodiment In the second embodiment, the area s (y) of the columnar spacer 1 16 is changed to satisfy the following formula, and a liquid crystal display panel having a uniform cell pitch deformation amount Δd〇 can be obtained. [Math 1 1] s(y) = (Patm-(P〇+/〇 · g* y))/(Ad〇· b- kps) (-h/2 ^ y ^ h/2)
最後針對上述第二實施形態來說明。在第二實施形態中 ，液晶顯示面板1 0係藉由例如隔牆3 0 a、3 0 b分割成a晶胞 、b晶胞、c晶胞的三個晶胞。各晶胞内的壓力分布寬△ h: 、△ hb、△ hc因都未滿大氣壓，故若使每一各晶胞柱狀間隔 物1 6的佔有率a(y)滿足上述數學式6，則可得到具有均勻的 晶胞間距的變形量△ d〇之本發明的液晶顯示面板。 在本實施例三中與上述實施例--樣，令柱狀間隔物Finally, the second embodiment will be described.

The pressure distribution width Δ h: , Δ hb , and Δ hc in each unit cell are less than atmospheric pressure. Therefore, if the occupancy rate a(y) of each of the unit cell column spacers 16 satisfies the above formula 6, Then, the liquid crystal display panel of the present invention having a uniform amount of deformation of the cell pitch Δd〇 can be obtained. In the third embodiment, in the same manner as the above embodiment, the column spacers are
16的面積s為一定，使其位置依存於柱狀間隔物16的密度 b(y)，以a(y) = s · b(y)。其結果得到下式數學式12。 [數學式12] b(y) = (Patm-(P〇+|0 · g· (y-ha/2)))/( Δ do · s· kps) (0^ ha) b(y) = (Patm-(P〇+/0 · g· (y-ha-hb/2)))/( Δ d〇 · s· kps) (ha ^ y ^ ha + hb) b(y) = (Patm-(P〇+P · g · (y-ha-hb-hc/2)))/( Δ d〇 · s · kps) -26-The area s of 16 is constant, and its position depends on the density b(y) of the column spacer 16, with a(y) = s · b(y). As a result, the following formula 12 is obtained. [Math 12] b(y) = (Patm-(P〇+|0 · g· (y-ha/2)))/( Δ do · s· kps) (0^ ha) b(y) = (Patm-(P〇+/0 · g· (y-ha-hb/2)))/( Δ d〇· s· kps) (ha ^ y ^ ha + hb) b(y) = (Patm- (P〇+P · g · (y-ha-hb-hc/2)))/( Δ d〇· s · kps) -26-
