膜234 ’在第2層積膜32中之第2層折射率膜322及第4 層折射率膜324的膜厚,宜分別為200nm以下,更佳為 150nm以下。 第2透明電極33之膜厚宜為1〇〜30nm,更佳為 15〜25nm,特佳為18〜22nm。 根據如此液晶面板1,因為在第丨基板部2具有特定構成 的第1層積膜23,同時在第2基板部3具有特定構成的第2層 積膜32,因此,相較於習知僅在一者之基板部上具有層積 臈者,能使各色之光的穿透率提高,且亦能抑制各色之穿 透率的變動。 具體s之’可使波長為450nm、550nm及650nm之光的 穿透率為87%以上。再者,可使以波長在4〇〇〜7〇〇nm範圍内 之光穿透率之最大值與最小值的差所表示變動值在1〇%以 下’較佳在5%以下。另,例如以波長為4〇〇〜7〇〇nm範圍的 光穿透率之最大值為90%、最小值為86°/。的情況下,變動值 能求出其值為90%-86%=4%。 例如,在如習知般於作為基板本體的石英基板,直接 層積作為透明電極之IT〇(lndium Tin Oxide)膜的情況下,因 為石英基板的折射率約為1.46,且ΐτο膜的折射率為2左 右,所以因其等折射率的不同,未必能得到充足的穿透率。 再者,雖然僅在構成液晶面板之一對石英基板的一者上設 201224592 置用以提1¾穿透率的層積膜係為已知,然而,有關在~對 石英基板的兩者上設置層積膜時的效果,或是在各層積膜 中之各個折射率膜的最適膜厚等,則未必明確。 根據上述液晶面板1,在第1基板部2設置第1層積膜 23,同時在第2基板部3設置第2層積膜32,藉由將第1層積 膜23、第2層積膜32之各別的層數及各折射率膜的膜厚予以 特定,係有效地緩和第1基板本體21與第1透明電極24之折 射率差’以及第2基板本體31與第2透明電極33之折射率 差,而能使液晶面板1整體的穿透率提高的同時,亦能抑制 穿透率的變動。再者,因為相較於習知之液晶面板未必增 加大的製造步驟,因而能確保生産性能。 在第1層積膜23或第2層積膜32中之折射率膜的層數為 不足6層的情況下,恐有r、g、B各色波長的光穿透率不會 充分地提高,且其變動亦無法充分地抑制之虞。倘若第!層 積膜23、第2層積膜32中之折射率膜的層數為6層,即可充 分地提高R、G、B各色波長的光穿透率,且亦能充分地抑 制其變動。本發明中’只要達到上述之層數,亦可具有其 以上之層數’但是’在層數過多的情況下,恐有增加製造 步驟,而降低生産性能之虞。 再者,在第1層積膜23或第2層積膜32中之第1至6層之 任一層的折射率膜的膜厚落在上述範圍外的情況下,即使 折射率膜的層數為6層,也未必可充分地提高尺、G、B之各 色波長的光穿透率,也無法充分地抑制其變動。另,在折 射率膜的膜厚超過上述範圍的情況下,恐有無法充分地提 12 201224592 间R、g、b之各色波長的光穿透率也無法充分地抑制其 ’ S J·隨著成膜時間的増加,恐有降低生産性 之虞。 第1基板本體21、+ 弟2基板本體31,只要由透光性材料 ^ P可未必文到限制,例如雖能使用結晶化玻璃, 门穿透率及低熱膨脹的理由最適於使用石英基板。 再者’有關其等之厚声, / 又雖未必受到限制,一般宜為

The refractive index film 321 of the first layer of the second laminated film 32 is 1 to 26 nm, more preferably 2 to 15 nm, and the refractive index film 322 of the second layer is 1 to 100 nm, more preferably 60 to 75 nm, and the third layer. The refractive index film 323 is 1 to 30 nm, more preferably 5 to 20 nm, the fourth layer of the refractive index film 324 is 1 to 100 nm, more preferably 60 to 70 nm, and the fifth layer of the refractive index film 325 is 10 201224592 2~ 41 nm' is more preferably ι 〇 25 nm, and the refractive index film 326 of the sixth layer is 6 to 95 nm, more preferably 4 Å to 55 nm. The second-layer refractive index film 232 in the first laminated film 23 and the second-layer refractive index film in the second laminated film 32 in the first laminated film 23 are usually viewed from the viewpoint of production performance and the like. The film thickness of the 322 and the fourth-layer refractive index film 324 is preferably 200 nm or less, and more preferably 150 nm or less. The film thickness of the second transparent electrode 33 is preferably from 1 to 30 nm, more preferably from 15 to 25 nm, particularly preferably from 18 to 22 nm. According to the liquid crystal panel 1, the first laminated film 23 having a specific configuration is provided in the second substrate portion 2, and the second laminated film 32 having a specific configuration is provided in the second substrate portion 3, so that only the conventional laminated film 32 is used. If one of the substrate portions has a laminate, the transmittance of light of each color can be improved, and the variation in the transmittance of each color can be suppressed. Specifically, the transmittance of light having wavelengths of 450 nm, 550 nm, and 650 nm can be 87% or more. Further, the variation value of the difference between the maximum value and the minimum value of the light transmittance in the range of 4 〇〇 to 7 〇〇 nm in wavelength can be expressed by less than 1% by weight, preferably 5% or less. Further, for example, the maximum value of the light transmittance in the range of 4 〇〇 to 7 〇〇 nm is 90%, and the minimum value is 86 °/. In the case of a variable value, the value can be found to be 90%-86%=4%. For example, in the case of an IT substrate (lndium Tin Oxide) film which is a transparent electrode as a quartz substrate as a substrate body as in the prior art, the refractive index of the quartz substrate is about 1. 46, and the refractive index of the ΐτ film is about 2, so it is not always possible to obtain sufficient transmittance due to the difference in the equal refractive index. Furthermore, although it is known to provide a laminated film for the transmittance of 201224592 which is one of the liquid crystal panels and one of the quartz substrates, it is known to be disposed on both of the quartz substrates. The effect at the time of laminating the film or the optimum film thickness of each of the refractive index films in each laminated film is not necessarily clear. According to the liquid crystal panel 1, the first laminated film 23 is provided in the first substrate portion 2, and the second laminated film 32 is provided in the second substrate portion 3, and the first laminated film 23 and the second laminated film are formed. The respective number of layers of 32 and the film thickness of each of the refractive index films are specified to effectively alleviate the difference in refractive index between the first substrate body 21 and the first transparent electrode 24, and the second substrate body 31 and the second transparent electrode 33. The difference in refractive index makes it possible to improve the transmittance of the liquid crystal panel 1 as a whole, and also to suppress variations in the transmittance. Further, since the manufacturing process is not necessarily increased as compared with the conventional liquid crystal panel, the production performance can be ensured. When the number of layers of the refractive index film in the first laminated film 23 or the second laminated film 32 is less than six, the light transmittance of the respective color wavelengths of r, g, and B may not be sufficiently improved. And its changes can not be fully suppressed. If the first! When the number of layers of the refractive index film in the laminated film 23 and the second laminated film 32 is six, the light transmittance of each of the R, G, and B wavelengths can be sufficiently increased, and the fluctuation can be sufficiently suppressed. In the present invention, the number of layers may be equal to or greater than the number of layers described above. However, when the number of layers is too large, the number of layers may be increased, and the production process may be increased to lower the production performance. In the case where the film thickness of the refractive index film of any of the first to sixth layers of the first laminate film 23 or the second laminate film 32 falls outside the above range, even if the number of layers of the refractive index film is In the case of six layers, it is not always possible to sufficiently increase the light transmittance of the respective color wavelengths of the ruler, G, and B, and it is not possible to sufficiently suppress the variation. When the film thickness of the refractive index film exceeds the above range, there is a fear that the light transmittance of the wavelengths of R, g, and b between 201224592 cannot be sufficiently raised, and the 'SJ· is not sufficiently suppressed. The increase in membrane time may lead to a reduction in productivity. The first substrate body 21 and the second substrate body 31 may not be limited by the light transmissive material. For example, crystallized glass can be used, and the reason for the gate transmittance and the low thermal expansion is most suitable for using a quartz substrate. Further, the thicker sound and/or the like are not necessarily limited, and it is generally preferable that the first substrate body 21 and the second substrate body 31 have mutually different materials and thicknesses.

In the case of a multilayer film, 3 constituting the multilayer film may be composed of the above-mentioned south refractive index material.

The low refractive index film of 叮立...(10) is also high. The refractive index film is the same, and may be composed of a low refractive index material which is different from each other (4).
