Ratio)、快速反應與廣視角等特性，為了克服大 尺寸液晶顯示面板的視角問題，液晶顯示面板的廣視角技 術也必須不停地進步與突破。其中，以多域垂直配向式 (Multi-domain Vertical Alignment mode，MVA mode )的液 晶顯示面板為目前較為常見的廣視角技術，如多域垂直配 向式(Multi-domain Vertical Alignment, MVA)液晶顯示面 板、聚合物穩定配向（Polymer Stabilized Alignment, PSA) 液晶顯示面板等。 以多域垂直配向式液晶顯示面板而言，其例如是在晝 素電極上形成多個條狀狹缝(slit)，並在相對之彩色濾光陣 列基板上配置多個條狀凸起物(pr〇trusi〇n) ’以藉由狹縫與 突起物的搭配’使得液晶層内的液晶分子呈現多方向的傾 倒’而達到廣視角顯示的效果。 美國專利公開號US2009/0086144A1“液晶顯示面板，， 揭露了一種習知的聚合物穩定配向液晶顯示面板的晝素結 201133094 2〇yy-i-p-D-031TW 33329twf.doc/n 構。请參照圖卜晝素結構1〇〇包括主動元件n〇、112與 晝素電極120、122 ’其中主動元件11〇、112與對應的掃 描線102及資料線1〇4電性連接，而晝素電極12〇、122 分別與主動元件110、112電性連接。如圖i所示，晝素電 極120與晝素電極122之間具有v型主狹縫13〇，以及晝 素電極120、122分別具有多個配向狹缝124。配向狭缝124 用以控制液晶顯示面板中液晶分子的排列方向。其中，各 個晝素電極120、122之配向狹缝124的延伸方向大致上區 分為四個方向，因此畫素電極12〇以及晝素電極122所在 位置分別可劃分出四個不同配向領域的配向區域I、η、 III、IV。 特別注意到的是’ V型主狹缝130位於晝素電極120 之配向區域III與晝素電極122之配向區域π之間以及晝 素電極120之配向區域iv與晝素電極122之配向區域I 之間’而晝素電極120之配向區域ΙΠ的配向方向與晝素 電極122之配向區域π的配向方向不同，以及晝素電極12〇 之配向區域IV的配向方向與晝素電極122之配向區域I 的配向方向不同。也就是說’位於V型主狹缝130附近的 配向區域具有不同的配向方向。由於液晶分子會沿著其所 在位置之配向區域的配向方向排列，因此，如圖i所示， 與晝素電極120之配向區域ΙΠ、IV相鄰的液晶分子lC的 傾倒方向會平行於晝素電極12〇之配向區域j、π的配向 狹缝124的延伸方向，而與晝素電極122之配向區域「η 相鄰的液晶分子LC的傾倒方向會平行於晝素電極122之 201133094 2009-I-P-D-031TW 33329twf.doc/n 配向區域I、II的配向狹缝124的延伸方向。由圖1可知， 位於V型主狹缝130兩側的液晶分子LC具有顯著不同的 傾倒方向，使得位於V型主狹缝130附近的液晶分子LC 會處於兩種傾倒方向之間的過度態。如此一來，當晝素結 構100在進行顯示時，這些處於過度態旋轉角度的液晶分 子會導致V型主狹縫130處有暗紋產生，使液晶顯示器有 顯示亮度不均勻的問題。 【發明内容】

Description of the Invention: [Technical Field] The present invention relates to a halogen structure and a liquid crystal display, and particularly relates to a display quality Pixel structure and liquid crystal display [Prior Art] As the display specifications of liquid crystal displays continue to move toward large size, the performance requirements of liquid crystal displays in the market are toward high contrast (High Contrast Ratio), fast response and wide viewing angle. In order to overcome the viewing angle problem of large-size liquid crystal display panels, the wide viewing angle technology of liquid crystal display panels must also continue to advance and break through. Among them, the multi-domain vertical alignment mode (MVA mode) liquid crystal display panel is a relatively common wide viewing angle technology, such as a multi-domain vertical alignment (MVA) liquid crystal display panel. , Polymer Stabilized Alignment (PSA) liquid crystal display panel, etc. In the multi-domain vertical alignment liquid crystal display panel, for example, a plurality of strip slits are formed on the pixel electrode, and a plurality of strip protrusions are disposed on the opposite color filter array substrate ( Pr〇trusi〇n) 'to make the liquid crystal molecules in the liquid crystal layer appear multi-directional dumping by the combination of slits and protrusions' to achieve a wide viewing angle display effect. U.S. Patent Publication No. US2009/0086144A1, "Liquid Crystal Display Panel," discloses a conventional polymer-stabilized alignment liquid crystal display panel of 昼素结201133094 2〇yy-ipD-031TW 33329twf.doc/n. Please refer to Figure 昼The element structure 1〇〇 includes an active device n〇, 112 and a halogen electrode 120, 122′, wherein the active device 11〇, 112 is electrically connected to the corresponding scan line 102 and the data line 1〇4, and the halogen electrode 12〇, 122 is electrically connected to the active elements 110 and 112 respectively. As shown in FIG. i, the v-shaped main slit 13 is provided between the halogen electrode 120 and the halogen electrode 122, and the halogen electrodes 120 and 122 respectively have a plurality of alignments. a slit 124. The alignment slit 124 is used to control the alignment direction of the liquid crystal molecules in the liquid crystal display panel, wherein the extending direction of the alignment slits 124 of the respective pixel electrodes 120 and 122 is substantially divided into four directions, and thus the pixel electrode 12〇 and the position of the halogen electrode 122 can respectively define the alignment regions I, η, III, IV of four different alignment fields. It is particularly noted that the 'V-type main slit 130 is located in the alignment region III of the halogen electrode 120. Alizarin Between the alignment regions π of 122 and between the alignment regions iv of the halogen electrodes 120 and the alignment regions I of the halogen electrodes 122, and the alignment direction of the alignment regions ΙΠ of the halogen electrodes 120 and the alignment region π of the halogen electrodes 122 The alignment direction is different, and the alignment direction of the alignment region IV of the halogen electrode 12 is different from the alignment direction of the alignment region I of the halogen electrode 122. That is, the alignment regions located near the V-shaped main slit 130 have different alignments. Since the liquid crystal molecules are arranged along the alignment direction of the alignment region at the position where they are located, as shown in FIG. 1, the tilting direction of the liquid crystal molecules 1C adjacent to the alignment regions ΙΠ, IV of the halogen electrode 120 is parallel to The alignment direction of the alignment slits 124 of the alignment regions j and π of the halogen electrode 12〇, and the tilt direction of the liquid crystal molecules LC adjacent to the alignment region “n” of the halogen electrode 122 is parallel to the pixel electrode 122 of 201133094 2009 -IPD-031TW 33329twf.doc/n The direction in which the alignment slits 124 of the alignment regions I and II extend. As can be seen from Fig. 1, the liquid crystal molecules LC located on both sides of the V-type main slit 130 have significantly different dumping The direction is such that the liquid crystal molecules LC located in the vicinity of the V-shaped main slit 130 are in an excessive state between the two tilting directions. Thus, when the halogen structure 100 is being displayed, these liquid crystal molecules are in an excessive rotation angle. There is a problem that dark lines are generated at the V-shaped main slit 130, which causes the liquid crystal display to have uneven display brightness.
