【0003】対向電極にスリットを形成した液晶表示装置を図4に基づいて説明する。 [0003] be described with reference to a liquid crystal display device in which a slit is formed on the counter electrode in FIG. 図4は従来の液晶表示装置における電圧印加時の断面概略図である。 Figure 4 is a cross-sectional schematic view of when a voltage is applied in a conventional liquid crystal display device. 100はガラス基板などの透明な基板、101は基板100上に形成された信号線、102は画素毎に設けられた画素電極、103は基板100上に積層された配向膜である。 100 transparent substrate such as a glass substrate, 101 is a signal line formed on the substrate 100, 102 is a pixel electrode provided for each pixel, 103 are oriented film laminated on the substrate 100.
104は基板100に対向配置された透明な基板、10 104 transparent substrate arranged to face the substrate 100, 10
5は各画素間に配置された遮光膜、106は各画素に対応したカラーフィルタ、107はカラーフィルタ106 5 light-shielding film disposed between the pixels, the color filter 106 corresponding to each pixel, the 107 color filter 106
に積層された平坦化膜、108は画素電極102の中央部に対向する部分にスリット111が設けられた対向電極、109は対向電極108及び平坦化膜107を覆う配向膜である。 Laminated on the planarizing film, 108 a counter electrode slits 111 is provided at a portion facing the central portion of the pixel electrode 102, 109 is a alignment film covering the opposing electrode 108 and the planarization film 107. 一対の基板100、104間には液晶1 The liquid crystal between the pair of substrates 100, 104 1
10が挟持され、画素電極102に印加される電圧に応じて配列状態が変化する。 10 is sandwiched, arranged state changes in accordance with the voltage applied to the pixel electrode 102. 例えば液晶110が負の誘電率異方性を持ち、配向膜103、109に垂直配向処理を施した場合、電圧無印加時は液晶分子110が配向膜103、109に影響されて垂直配列になり、電界印加時は液晶分子110が画素電極102と対向電極108 For example, a liquid crystal 110 has a negative dielectric anisotropy, when subjected to vertical alignment treatment to the alignment film 103 and 109, when no voltage is applied becomes vertically aligned liquid crystal molecules 110 is affected by the alignment films 103 and 109 , when an electric field is applied the liquid crystal molecules 110 and the pixel electrode 102 opposite electrode 108
間に生じる電界に影響されて水平方向へ傾斜する。 It is influenced inclined toward the horizontal direction to the electric field generated between. このとき対向電極108にはスリット111が形成されているため、画素電極102の周縁部や対向電極108のスリット111部分では図4の点線で示すように基板10 Since the slits 111 are formed in the counter electrode 108 at this time, the substrate 10 as the slit 111 portion of the peripheral edge and the counter electrode 108 of the pixel electrode 102 shown by a dotted line in FIG. 4
0、104に対して斜め方向に電界が発生し、1画素内に液晶分子の傾斜方向の異なる領域ができる。 An electric field is generated in a direction oblique to 0,104, it is the inclination direction different regions of the liquid crystal molecules in one pixel.

【0004】 [0004]

【発明が解決しようとする課題】対向電極108にスリット111を形成しない場合であれば平坦化膜107を設けなくてもよいが、対向電極108にスリット111 Although it is not necessary to provide a flattening film 107 in the case of not forming the slit 111 to the counter electrode 108 [0005], the slit 111 to the counter electrode 108
を形成する場合はカラーフィルタ106上に平坦化膜1 When forming a flat on the color filter 106 film 1
07などのカラーフィルタ106を覆う膜が必要となる。 Film covering the color filters 106, such as 07 is required. 例えばスリット111部分に平坦化膜107がないとき、スリット111部分でカラーフィルタ106が配向膜109を介して液晶に接することになり、カラーフィルタ106の成分が配向膜109を通って液晶110 For example, when there is no planarization layer 107 in the slit 111 portion, a color filter 106 becomes in contact with the liquid crystal with the alignment film 109 at the slit 111 parts, the liquid crystal 110 components of the color filter 106 through the orientation film 109
に溶けこんでしまう。 Become crowded soluble in. そのため液晶110が汚れるなどの不具合が生じ、表示の品質が低下してしまう。 Therefore trouble occurs, such as a liquid crystal 110 is contaminated, the quality of display is degraded. そこでスリット111部分のカラーフィルタ106上に平坦化膜107を積層することで、カラーフィルタ106の成分が液晶110に溶け出すことを防止している。 Therefore by laminating a planarizing film 107 over the slit 111 portion of the color filter 106, and prevents the components of the color filters 106 from dissolving in the liquid crystal 110. このように対向電極108にスリット111を形成する場合はスリット111部分に平坦化膜107などを必要とするが、この平坦化膜107を積層するための製造工程が増えてしまう。 This way when forming the slit 111 to the counter electrode 108 requires such planarization layer 107 in the slit 111 portion, thus increasing manufacturing steps for laminating the planarization film 107.

【0005】そこで本発明は、平坦化膜などを設けることなく対向電極にスリットを形成した液晶表示装置を提案する。 [0005] The present invention proposes a liquid crystal display device in which a slit is formed on the counter electrode without providing the like planarizing film.

【課題を解決するための手段】上記課題を解決するために本発明は、一対の基板間に封入した液晶と、一方の基板上に画素毎に形成した画素電極と、他方の基板に形成すると共に前記画素電極に対向配置したカラーフィルタと、前記カラーフィルタ上に積層した対向電極と、各画素に応じて前記対向電極に形成したスリットとを備え、 Means for Solving the Problems The present invention to solve the above problems, a liquid crystal sealed in between a pair of substrates, a pixel electrode formed for each pixel on one substrate is formed on the other substrate comprising a color filter disposed opposite to the pixel electrode, a counter electrode are laminated on the color filter, and a slit formed in the counter electrode in accordance with each pixel with,

【発明の実施の形態】以下、本発明の実施形態を図に基づいて説明する。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, will be described with reference to FIG embodiments of the present invention. 図1は第一基板側の平面図、図2は図1のA−A線に沿った断面概略図である。 Figure 1 is a plan view of the first substrate side, FIG. 2 is a sectional schematic view taken along the line A-A of FIG.

【0008】1はガラス基板などの透明な第一基板であり、この第一基板1上には走査線2と信号線3がマトリクス状に配線され、走査線2と信号線3で囲まれる領域に画素電極4が配置されている。 [0008] 1 is a transparent first substrate such as a glass substrate, this first substrate 1 has a scanning line 2 and the signal lines 3 are wired in a matrix, a region surrounded by the scanning line 2 and the signal line 3 pixel electrodes 4 are disposed. 走査線2と信号線3の交差部にはTFT5(薄膜トランジスタ)が形成され、 The intersection of the scanning line 2 and the signal lines 3 are formed TFT 5 (thin film transistor) is,
TFT5のゲート電極は走査線2に、TFT5のソース電極は信号線3に、TFT5のドレイン電極は画素電極4にそれぞれ接続されている。 The gate electrode of the TFT5 to the scanning line 2, the source electrode of the TFT5 to the signal line 3, the drain electrode of the TFT5 is connected to the pixel electrode 4. 6は垂直配向処理が施された配向膜であり、画素電極4に積層されている。 6 is a alignment film vertically aligned process is performed, it is stacked on the pixel electrode 4.

【0011】基板1、7間には負の誘電率異方性を有する液晶12が挟持され、電圧無印加時には配向膜6、1 [0011] Between the substrate 1 and 7 a liquid crystal 12 having a negative dielectric anisotropy is sandwiched, orientation when no voltage is applied film 6,1
1の作用を受けて垂直配列する。 Vertically arranged under the action of 1. 画素電極4に電圧が印加されると、画素電極4と対向電極10の間に電界が発生し、その電界に影響されて液晶分子12が垂直方向から水平方向へ傾斜する。 When a voltage to the pixel electrode 4 is applied, an electric field is generated between the pixel electrode 4 and the counter electrode 10, liquid crystal molecules 12 are influenced by the electric field is inclined from the vertical direction to the horizontal direction. このとき画素電極4の周縁部や対向電極10のスリット13部分では図2の点線で示すように基板1、7に対して斜め方向の電界が発生し、液晶分子12はこの電界の方向によって傾斜方向が規制される。 In this case the slit 13 portion of the peripheral edge and the counter electrode 10 of the pixel electrode 4 field in an oblique direction occurs for the substrate 1, 7, as shown by the dotted line in FIG. 2, the liquid crystal molecules 12 are tilted by the orientation of the electric field direction is restricted. スリット13部分の対向電極10では電界がその端部からスリット13中央の方向へ広がりながら画素電極4まで発生し、図2に示すようにスリット13の左側に位置する液晶分子12は時計回りに傾斜し、スリット13の右側に位置する液晶分子12は半時計回りに傾斜する。 Field in the counter electrode 10 of the slit 13 portion is generated to the pixel electrode 4 while spreading from the end portion into the slit 13 center direction, the liquid crystal molecules 12 located on the left side of the slit 13 as shown in FIG. 2 is inclined clockwise and, the liquid crystal molecules 12 located on the right side of the slit 13 is inclined counterclockwise. このスリット13付近の液晶分子12の傾斜方向が周りの液晶分子12に影響して、各液晶分子12は隣接する液晶分子12とほぼ同じ方向に傾斜する。 This affects the liquid crystal molecules 12 around the tilt direction of the liquid crystal molecules 12 in the vicinity of the slit 13, the liquid crystal molecules 12 are inclined substantially in the same direction as the liquid crystal molecules 12 adjacent. そしてスリット13を挟んで隣接する領域の液晶分子12が互いに逆方向に傾斜し、この実施形態では1画素をスリット13で4つの領域に分割しているため、各領域の液晶分子12がその傾斜方向に対応する方向の視野角を改善し、広視野角の液晶表示装置になる。 And inclined in opposite direction the liquid crystal molecules 12 in the adjacent regions to each other across the slit 13, because it is divided into four regions one pixel in the slit 13 in this embodiment, the liquid crystal molecules 12 in each region the inclination improving the viewing angle of the direction corresponding to the direction, the liquid crystal display device of wide viewing angle.
