Description

本開示は、表示装置に関し、例えばインセル型タッチパネルを有する表示装置に適用可能である。   The present disclosure relates to a display device, and is applicable to a display device having an in-cell touch panel, for example.

近年、モバイル用途の液晶表示装置ではスマートフォン向けを中心に入力機能としての静電容量タッチパネルが導入されている。さらにこの静電容量タッチパネルは、液晶表示装置内にその機能を組み込むインセル化がすすめられている。インセル化において、活用されているのが、FFS(フリンジフィールドスイッチング)構造の共通電極である。共通電極は、TFT(Thin Film Transistor)ガラス基板上にITO(Indium Tin Oxide)で形成され、タッチパネルの駆動電極を兼ねている。検出電極はCF(Color Filter)ガラス基板上の裏面にITOで形成されている。   In recent years, a liquid crystal display device for mobile use has introduced a capacitive touch panel as an input function mainly for smartphones. Furthermore, this capacitive touch panel is being promoted to be in-cell that incorporates its function in the liquid crystal display device. A common electrode having an FFS (fringe field switching) structure is utilized in the in-cell structure. The common electrode is formed of ITO (Indium Tin Oxide) on a TFT (Thin Film Transistor) glass substrate and also serves as a drive electrode for the touch panel. The detection electrode is formed of ITO on the back surface of a CF (Color Filter) glass substrate.

特開2009−244958号公報(特許文献1)においては、ゲート線方向に分割された共通電極は、ソース線方向に分割されたた検出電極と組み合わせられて、タッチパネルの機能が実現されている。なお、共通電極の分割方向として、特開2010−231773号公報(特許文献2)や国際公開第2012/073792号(特許文献3)に開示されるように、ソース線方向に分割する方法もある。   In Japanese Patent Application Laid-Open No. 2009-244958 (Patent Document 1), the common electrode divided in the gate line direction is combined with the detection electrode divided in the source line direction to realize the function of the touch panel. In addition, as a dividing direction of the common electrode, there is a method of dividing in the source line direction as disclosed in Japanese Patent Application Laid-Open No. 2010-231773 (Patent Document 2) and International Publication No. 2012/073792 (Patent Document 3). .

本願発明者は、共通電極配線層をソース配線層方向に分割する場合、次のような問題があることを見出した。
共通電極配線層をゲート配線層方向に分割する場合は、共通電極配線層の抵抗を下げる目的で共通電極配線層とコンタクトする形で、すべてのソース配線層上でBM(ブラックマトリックス)下になる位置に金属配線層を配置すると、TFTガラス基板とCFガラス基板の組立ずれが生じた場合に生じる視野角混色を防止することができる。しかし、共通電極配線層をソース配線層方向に分割する場合、共通電極配線層の分割位置には金属配線層を配置することができなくなり、視野角混色が生じる可能性がある。
本開示の課題は、視野角混色が少ない表示装置を提供することである。
その他の課題と新規な特徴は、本開示の記述および添付図面から明らかになるであろう。
The inventor of the present application has found that there are the following problems when the common electrode wiring layer is divided in the direction of the source wiring layer.
When the common electrode wiring layer is divided in the direction of the gate wiring layer, it is in contact with the common electrode wiring layer for the purpose of reducing the resistance of the common electrode wiring layer, and is below the BM (black matrix) on all the source wiring layers. When the metal wiring layer is disposed at the position, it is possible to prevent viewing angle color mixing that occurs when the TFT glass substrate and the CF glass substrate are misassembled. However, when the common electrode wiring layer is divided in the source wiring layer direction, the metal wiring layer cannot be arranged at the division position of the common electrode wiring layer, and there is a possibility that viewing angle color mixing occurs.
The subject of this indication is providing the display apparatus with few viewing angle color mixing.
Other problems and novel features will become apparent from the description of the present disclosure and the accompanying drawings.

本開示のうち、代表的なものの概要を簡単に説明すれば、下記のとおりである。
すなわち、表示装置は、共通電極配線層をソース配線層方向に分割し、ソース配線層の上方であって共通電極配線層の上に接する部分に金属配線層を配置し、共通電極配線層の分割位置には金属配線層を配置しない。ソース配線層の上方であるが、共通電極配線層の分割位置の色間と同色の色間には金属配線層を配置しないようにしてもよい。
The outline of a representative one of the present disclosure will be briefly described as follows.
That is, the display device divides the common electrode wiring layer in the source wiring layer direction, disposes the metal wiring layer above the source wiring layer and in contact with the common electrode wiring layer, and divides the common electrode wiring layer. The metal wiring layer is not disposed at the position. Although it is above the source wiring layer, the metal wiring layer may not be disposed between the colors of the same color as the divided positions of the common electrode wiring layer.

上記の表示装置によれば、視野角混色を低減することができる。   According to the above display device, viewing angle color mixing can be reduced.

まず、本願発明者が見出した視野角混色の問題について説明する。
図1は比較例1に係る表示装置の構成を示す図である。図1(a)は液晶表示装置の一部を示した平面図、同図(b)は同図(a)のA−A’線に沿った液晶表示装置の一部を示した断面図である。比較例1に係る表示装置11は、TFTガラス基板12、CFガラス基板13、およびTFTガラス基板12とCFガラス基板13間に挟まれた液晶層21を有する。TFTガラス基板12において、共通電極配線層14はゲート配線層と平行な方向(X方向)で分割されており、各サブピクセル間には共通電極配線層14と接続する形で金属配線層15が敷設されている。共通電極配線層14と共通電極配線層14との間の分割領域(分割位置)20はX方向に延在し、Y方向に周期的に配置される。金属配線層15は高精細パネルにおいて、CFガラス基板13とTFTガラス基板12の組立ずれが起きたときに生じる視野角混色を防止する遮光層の役割と共通電極配線層14の抵抗低減する役割を兼ねている。この構成の場合共通電極配線層14の分割位置は不図示の映像線(ゲート配線層)の上方にあるため、ゲート配線層との交差部の一部を除く、信号線(ソース配線層)16の上部には金属配線層15をすべて配置することができる。すなわち、すべての信号配線層16上でBM17下になる位置に金属配線層15が形成されている。
First, the problem of viewing angle color mixing discovered by the present inventor will be described.
FIG. 1 is a diagram illustrating a configuration of a display device according to Comparative Example 1. FIG. 1A is a plan view showing a part of the liquid crystal display device, and FIG. 1B is a cross-sectional view showing a part of the liquid crystal display device along the line AA ′ in FIG. is there. The display device 11 according to the comparative example 1 includes a TFT glass substrate 12, a CF glass substrate 13, and a liquid crystal layer 21 sandwiched between the TFT glass substrate 12 and the CF glass substrate 13. In the TFT glass substrate 12, the common electrode wiring layer 14 is divided in a direction (X direction) parallel to the gate wiring layer, and the metal wiring layer 15 is connected to the common electrode wiring layer 14 between the sub-pixels. It is laid. Divided regions (divided positions) 20 between the common electrode wiring layer 14 and the common electrode wiring layer 14 extend in the X direction and are periodically arranged in the Y direction. The metal wiring layer 15 has a role of a light shielding layer for preventing color mixing of viewing angles and a resistance reduction of the common electrode wiring layer 14 when an assembly error occurs between the CF glass substrate 13 and the TFT glass substrate 12 in a high-definition panel. Also serves as. In the case of this configuration, since the division position of the common electrode wiring layer 14 is above a video line (gate wiring layer) (not shown), the signal line (source wiring layer) 16 excluding a part of the intersection with the gate wiring layer. All of the metal wiring layer 15 can be disposed on the upper portion of the substrate. That is, the metal wiring layer 15 is formed at a position below the BM 17 on all the signal wiring layers 16.

CFガラス基板18は、赤(R)、緑(G)、青(B)のカラーフィルタ(着色層)18とBM17を有する。カラーフィルタ18は、行方向(X方向)にR、G、Bの順に繰り返し配置される。また、カラーフィルタ18は、列方向に同色が配置される。カラーフィルタは平面視で、X方向の長さがY方向の長さより短い矩形形状をしている。   The CF glass substrate 18 includes red (R), green (G), and blue (B) color filters (colored layers) 18 and a BM 17. The color filter 18 is repeatedly arranged in the order of R, G, and B in the row direction (X direction). The color filters 18 are arranged in the same color in the column direction. The color filter has a rectangular shape whose length in the X direction is shorter than the length in the Y direction in plan view.

CFガラス基板18の裏面(図1(b)においては上面)に不図示の検出電極配線層がソース配線層16と平行な方向(Y方向)に延在し、X方向に周期的に配置されている。   A detection electrode wiring layer (not shown) extends in the direction parallel to the source wiring layer 16 (Y direction) on the back surface (upper surface in FIG. 1B) of the CF glass substrate 18 and is periodically arranged in the X direction. ing.

共通電極配線層14および画素電極配線層19はITO等の透光金属層で形成され、金属配線層15およびソース配線層16は遮光金属層で形成される。   The common electrode wiring layer 14 and the pixel electrode wiring layer 19 are formed of a light-transmitting metal layer such as ITO, and the metal wiring layer 15 and the source wiring layer 16 are formed of a light shielding metal layer.

図2Aは比較例2に係る表示装置の構成を示す図である。図2Bは比較例2に係る表示装置の混色を示す図である。図2A(a)は液晶表示装置の一部を示した平面図、同図(b)は同図(a)のA−A’線に沿った液晶表示装置の一部を示した断面図である。比較例に係る表示装置11Aは、TFTガラス基板12において、共通電極配線層14はソース配線層16と平行な方向(Y方向)に延在し、X方向に分割されて周期的に配置されており、各サブピクセル間には共通電極配線層14と接続する形で金属配線層15が配置されている。ただし、分割された共通電極配線層14同士をショートしないようにするために、共通電極配線層14の分割位置(分割領域)には金属配線層15は配置されていない。すなわち、共通電極配線層14の分割位置に位置するソース配線層16上でBM17下になる位置に金属配線層15が形成されない。その結果、CFガラス基板13とTFTガラス基板12の組立ずれ(以下、単に、「組立ずれ」という。)が起きたときに視野角混色が生じる可能性がある。なお、共通電極配線層14と共通電極配線層14との間の分割領域(分割位置)20はY方向に延在し、X方向に周期的に配置される。共通電極配線層14の分割位置20は、赤サブピクセルと緑サブピクセルの間である。分割された一つの共通電極配線層14のX方向は9サブピクセル(3画素)分となっている。分割された共通電極配線層14の間隔(分割領域の幅)は金属配線層15の幅よりも小さく、金属配線層15の幅はBM17の幅よりも小さい。共通電極配線層14はY方向には分割されていないので、共通電極配線層14は、Y方向に配置されるすべての画素に共通に使用される。   FIG. 2A is a diagram illustrating a configuration of a display device according to Comparative Example 2. FIG. 2B is a diagram illustrating color mixing of the display device according to Comparative Example 2. 2A (a) is a plan view showing a part of the liquid crystal display device, and FIG. 2 (b) is a cross-sectional view showing a part of the liquid crystal display device along the line AA ′ in FIG. 2 (a). is there. In the display device 11A according to the comparative example, on the TFT glass substrate 12, the common electrode wiring layer 14 extends in a direction parallel to the source wiring layer 16 (Y direction), and is divided periodically in the X direction. A metal wiring layer 15 is disposed between the sub-pixels so as to be connected to the common electrode wiring layer 14. However, in order not to short-circuit the divided common electrode wiring layers 14, the metal wiring layer 15 is not disposed at the division position (divided region) of the common electrode wiring layer 14. That is, the metal wiring layer 15 is not formed at a position below the BM 17 on the source wiring layer 16 positioned at the division position of the common electrode wiring layer 14. As a result, viewing angle color mixing may occur when the CF glass substrate 13 and the TFT glass substrate 12 are misaligned (hereinafter simply referred to as “assembly misalignment”). The divided regions (divided positions) 20 between the common electrode wiring layer 14 and the common electrode wiring layer 14 extend in the Y direction and are periodically arranged in the X direction. The division position 20 of the common electrode wiring layer 14 is between the red subpixel and the green subpixel. The X direction of one divided common electrode wiring layer 14 is 9 sub-pixels (3 pixels). The interval between the divided common electrode wiring layers 14 (the width of the divided region) is smaller than the width of the metal wiring layer 15, and the width of the metal wiring layer 15 is smaller than the width of the BM 17. Since the common electrode wiring layer 14 is not divided in the Y direction, the common electrode wiring layer 14 is used in common for all pixels arranged in the Y direction.

図3Aから図3Dは組立ずれが起きたときに視野角混色が生じる原理を説明するための図である。図3Aは赤サブピクセルのみに白電圧が印加された場合に組立ずれが起きないときの断面図である。図3Bは赤サブピクセルのみに白電圧が印加された場合に組立ずれが起きたときの断面図で、同図(a)はCFガラス基板が右にずれたときの断面図で、同図(b)はCFガラス基板が左にずれたときの断面図である。図3Cは緑サブピクセルのみに白電圧が印加された場合に組立ずれが起きたときの断面図で、同図(a)はCFガラス基板が右にずれたときの断面図で、同図(b)はCFガラス基板が左にずれたときの断面図である。図3Dは青サブピクセルのみに白電圧が印加された場合に組立ずれが起きたときの断面図で、同図(a)はCFガラス基板が右にずれたときの断面図で、同図(b)はCFガラス基板が左にずれたときの断面図である。   FIG. 3A to FIG. 3D are diagrams for explaining the principle that color mixing of viewing angles occurs when an assembly shift occurs. FIG. 3A is a cross-sectional view when no assembly deviation occurs when a white voltage is applied only to the red subpixel. FIG. 3B is a cross-sectional view when an assembly shift occurs when a white voltage is applied only to the red subpixel. FIG. 3A is a cross-sectional view when the CF glass substrate is shifted to the right. b) is a cross-sectional view when the CF glass substrate is shifted to the left. FIG. 3C is a cross-sectional view when an assembly shift occurs when a white voltage is applied only to the green subpixel, and FIG. 3A is a cross-sectional view when the CF glass substrate is shifted to the right. b) is a cross-sectional view when the CF glass substrate is shifted to the left. FIG. 3D is a cross-sectional view when an assembly shift occurs when a white voltage is applied only to the blue subpixel, and FIG. 3A is a cross-sectional view when the CF glass substrate is shifted to the right. b) is a cross-sectional view when the CF glass substrate is shifted to the left.

図3Aは赤サブピクセルのみに白電圧が印加され、組立ずれが起きていないので、BM17の中心に白電圧と黒電圧の境界が位置するので、混色が生じない。   In FIG. 3A, since the white voltage is applied only to the red sub-pixel and no assembly deviation occurs, the boundary between the white voltage and the black voltage is located at the center of the BM 17, so that no color mixing occurs.

図3B(a)の赤サブピクセルのみに白電圧が印加され、CFガラス基板13が右にずれたときは、白電圧が隣の青のカラーフィルタに近い所に位置する部分にはいずれも金属配線層15が配置されているため、光漏れが生じす、混色は生じない。図3B(b)の赤サブピクセルのみに白電圧が印加され、CFガラス基板13が左にずれたときに、白電圧が隣の緑のカラーフィルタに近い所に位置する部分には金属配線層15が配置されない箇所があり、TFTガラス基板12の赤サブピクセルに対応する液晶を透過した光が赤のカラーフィルタと緑のカラーフィルタを透過して赤に緑が混色する。しかし、赤サブピクセルと緑サブピクセルの境界に金属配線層15がある箇所では混色は生じない。   When a white voltage is applied only to the red sub-pixel in FIG. 3B (a) and the CF glass substrate 13 is shifted to the right, the white voltage is metal in any part located near the adjacent blue color filter. Since the wiring layer 15 is arranged, light leakage and color mixing do not occur. When a white voltage is applied only to the red sub-pixel of FIG. 3B (b) and the CF glass substrate 13 is shifted to the left, the metal wiring layer is located at a portion where the white voltage is located close to the adjacent green color filter. 15 is not disposed, and the light transmitted through the liquid crystal corresponding to the red subpixel of the TFT glass substrate 12 is transmitted through the red color filter and the green color filter, and green is mixed with red. However, color mixing does not occur where the metal wiring layer 15 is at the boundary between the red subpixel and the green subpixel.

図3C(a)の緑サブピクセルのみに白電圧が印加されCFガラス基板13が右にずれたときに、白電圧が隣の赤のカラーフィルタに近い所に位置する部分には金属配線層15が配置されない箇所があり、TFTガラス基板12の緑サブピクセルに対応する液晶を透過した光が緑のカラーフィルタと赤のカラーフィルタを透過して緑に赤が混色する。しかし、緑サブピクセルと赤サブピクセルの境界に金属配線層15がある箇所では混色は生じない。図3C(b)の緑サブピクセルのみに白電圧が印加され、CFガラス基板13が左にずれたときは、白電圧が隣の青のカラーフィルタに近い所に位置する部分にはいずれも金属配線層15が配置されているため、光漏れが生じす、混色は生じない。   When a white voltage is applied only to the green sub-pixel in FIG. 3C (a) and the CF glass substrate 13 is shifted to the right, the metal wiring layer 15 is located at a portion where the white voltage is located close to the adjacent red color filter. Is not disposed, and light transmitted through the liquid crystal corresponding to the green subpixel of the TFT glass substrate 12 passes through the green color filter and the red color filter, and red is mixed with green. However, color mixing does not occur where the metal wiring layer 15 is at the boundary between the green sub-pixel and the red sub-pixel. When a white voltage is applied only to the green sub-pixel in FIG. 3C (b) and the CF glass substrate 13 is shifted to the left, any portion of the white voltage located near the adjacent blue color filter is metal. Since the wiring layer 15 is arranged, light leakage and color mixing do not occur.

図3D(a)の青サブピクセルのみに白電圧が印加され、CFガラス基板13が右にずれたときは、白電圧が隣の緑のカラーフィルタに近い所に位置する部分にはいずれも金属配線層15が配置されているため、光漏れが生じす、混色は生じない。図3D(b)の青サブピクセルのみに白電圧が印加され、CFガラス基板13が左にずれたときは、白電圧が隣の赤のカラーフィルタに近い所に位置する部分にはいずれも金属配線層15が配置されているため、光漏れが生じす、混色は生じない。   When a white voltage is applied only to the blue subpixel in FIG. 3D (a) and the CF glass substrate 13 is shifted to the right, the white voltage is metal in any part located near the adjacent green color filter. Since the wiring layer 15 is arranged, light leakage and color mixing do not occur. When a white voltage is applied only to the blue sub-pixel in FIG. 3D (b) and the CF glass substrate 13 is shifted to the left, the white voltage is metal in any part located near the adjacent red color filter. Since the wiring layer 15 is arranged, light leakage and color mixing do not occur.

なお、共通電極配線層14の分割位置を赤サブピクセルと緑サブピクセルの間にした場合に、上記のような視野角混色が生じる。共通電極配線層14の分割位置を緑サブピクセルと青サブピクセルの間にした場合には、緑に青の混色または青に緑の混色が生じる。共通電極配線層14の分割位置を青サブピクセルと赤サブピクセルの間にした場合には、青に赤の混色または赤に青の混色が生じる。なお、透過率の高いサブピクセルで光漏れが生じると混色が悪化するため、透過率が最も高いサブピクセルの横での共通電極配線層の分割は避けた方がよい。白サブピクセル、緑サブピクセル、赤サブピクセル、青サブピクセルの順に透過率の高い。すなわち、白サブピクセルが最も透過率が高く、青サブピクセルが最も透過率が低い。   Note that when the division position of the common electrode wiring layer 14 is between the red sub-pixel and the green sub-pixel, the viewing angle color mixing as described above occurs. When the common electrode wiring layer 14 is divided between the green sub-pixel and the blue sub-pixel, a mixed color of blue with green or a mixed color of green with blue is generated. When the division position of the common electrode wiring layer 14 is between the blue sub-pixel and the red sub-pixel, a red mixed color of blue or a blue mixed color of red is generated. Note that if light leakage occurs in a subpixel having a high transmittance, color mixture deteriorates. Therefore, it is better to avoid dividing the common electrode wiring layer next to the subpixel having the highest transmittance. The transmittance is high in the order of white subpixel, green subpixel, red subpixel, and blue subpixel. That is, the white subpixel has the highest transmittance, and the blue subpixel has the lowest transmittance.

図2B(a)はCFガラス基板が右にずれた場合、同図(b)はCFガラス基板が左にずれた場合を示している。同図(ar)、(br)は液晶表示装置を右側から見た場合、同図(ac)、(bc)は液晶表示装置を正面から見た場合、同図(al)、(bl)は液晶表示装置を左側から見た場合を示している。同図(a1)、(b1)は赤サブピクセルのみに白電圧が印加された場合に組立ずれが起きたとき、同図(a2)、(b2)は緑サブピクセルのみに白電圧が印加された場合に組立ずれが起きたとき、同図(a3)、(b3)は青サブピクセルのみに白電圧が印加された場合に組立ずれが起きたときを示している。共通電極配線層14の分割位置、すなわち、金属配線層15がない箇所が周期的に配置されるので、同図(a2)(ar)に示すように緑色画面に赤色の縦筋が現れる可能性があり、同図(b1)(bl)に示すように赤色画面に緑色の縦筋が現れる可能性がある。   FIG. 2B (a) shows a case where the CF glass substrate is shifted to the right, and FIG. 2B shows a case where the CF glass substrate is shifted to the left. FIGS. 7A and 7B show the liquid crystal display device when viewed from the right side, FIGS. 5A and 5B show the liquid crystal display device when viewed from the front, and FIGS. The case where the liquid crystal display device is viewed from the left side is shown. (A1) and (b1) show that when a white voltage is applied only to the red sub-pixel and an assembly shift occurs, (a2) and (b2) show that the white voltage is applied only to the green sub-pixel. In the case where an assembly error occurs, FIGS. 3A and 3B show the case where an assembly error occurs when a white voltage is applied only to the blue subpixel. Since the division position of the common electrode wiring layer 14, that is, the portion where the metal wiring layer 15 is not provided is periodically arranged, there is a possibility that red vertical stripes appear on the green screen as shown in FIG. There is a possibility that green vertical stripes appear on the red screen as shown in FIGS.

以下、実施例および変形例について、図面を用いて説明する。ただし、以下の説明において、同一構成要素には同一符号を付し繰り返しの説明は省略する。   Hereinafter, examples and modifications will be described with reference to the drawings. However, in the following description, the same components are denoted by the same reference numerals, and repeated description is omitted.

図4は実施例1に係る液晶表示装置の構成を示す図である。図4(a)は液晶表示装置の基板ごとの平面図、同図(b)は側面図を示している。実施例1に係る液晶表示装置40は、インセルタイプのタッチパネル機能を有し、共通電極配線層がタッチパネルの駆動電極配線層の機能を兼ねている。   FIG. 4 is a diagram illustrating the configuration of the liquid crystal display device according to the first embodiment. 4A is a plan view of each substrate of the liquid crystal display device, and FIG. 4B is a side view. The liquid crystal display device 40 according to the first embodiment has an in-cell type touch panel function, and the common electrode wiring layer also functions as a drive electrode wiring layer of the touch panel.

共通電極配線層14は信号配線層16と平行な方向(Y方向)に延在し、X方向に分割されて周期的に配置されており、各サブピクセル間には共通電極配線層14と接続する形で金属配線層15が配置されている。ただし、分割された共通電極配線層14同士をショートしないようにするために、共通電極配線層14の分割位置(分割領域)には金属配線層15は配置されていない。すなわち、共通電極配線層14の分割位置に位置する信号配線層16上でBM17下になる位置に金属配線層15が形成されない。なお、共通電極配線層14と共通電極配線層14との間の分割領域(分割位置)20はY方向に延在し、X方向に周期的に配置される。また、共通電極配線層14の分割位置の色間と同じ色間の金属配線層15はすべて配置しない。画素電極層19がドレイン電極層56の接続するコンタクトホール部分を除いて、共通電極層14はサブピクセル間で接続されている。なお、図面記載上の都合により、分割された一つの共通電極配線層14のX方向は6サブピクセル(2画素)分となっているが、本実施例では、比較例2と同様に図6Aに示すように、分割された一つの共通電極配線層14のX方向は9サブピクセル(3画素)分である。また、分割された共通電極配線層14の間隔(分割領域の幅)は金属配線層15の幅よりも小さく、金属配線層15の幅はBM17の幅よりも小さい。   The common electrode wiring layer 14 extends in a direction parallel to the signal wiring layer 16 (Y direction), is divided in the X direction and is periodically arranged, and is connected to the common electrode wiring layer 14 between the sub-pixels. The metal wiring layer 15 is arranged in such a manner. However, in order not to short-circuit the divided common electrode wiring layers 14, the metal wiring layer 15 is not disposed at the division position (divided region) of the common electrode wiring layer 14. That is, the metal wiring layer 15 is not formed at a position below the BM 17 on the signal wiring layer 16 located at the division position of the common electrode wiring layer 14. The divided regions (divided positions) 20 between the common electrode wiring layer 14 and the common electrode wiring layer 14 extend in the Y direction and are periodically arranged in the X direction. Further, not all of the metal wiring layers 15 having the same color as the color at the division position of the common electrode wiring layer 14 are arranged. The common electrode layer 14 is connected between the subpixels except for the contact hole portion where the pixel electrode layer 19 is connected to the drain electrode layer 56. For convenience of drawing, the X direction of one divided common electrode wiring layer 14 is equivalent to 6 subpixels (2 pixels). In this embodiment, as in Comparative Example 2, FIG. As shown in FIG. 5, the X direction of one divided common electrode wiring layer 14 is 9 sub-pixels (3 pixels). The interval between the divided common electrode wiring layers 14 (the width of the divided region) is smaller than the width of the metal wiring layer 15, and the width of the metal wiring layer 15 is smaller than the width of the BM 17.

Source wiring layer 16 and drain wiring layer 56 are connected to semiconductor layer 53 through contact holes in interlayer insulating film layer 54. The common electrode wiring layer 14 is disposed on the source wiring layer 16 via the insulating film layer 55. A metal wiring layer 15 is disposed on the common electrode wiring layer 14 in contact with a portion located above the source wiring layer 16. A pixel electrode layer 19 is disposed on the common electrode wiring layer 14 via an interlayer insulating film layer 57. The pixel electrode layer 19 is connected to the drain electrode layer 56 through a contact hole in the insulating film layer 55. The pixel electrode layer 19 has a slit. The gate wiring layer 51 extends in the X direction and extends in the Y direction toward the semiconductor layer 53.

図6Aは実施例1に係る液晶表示装置の構成を示す図である。図6Bは実施例1に係る液晶表示装置の混色を示す図である。図6A(a)は液晶表示装置の一部を示した平面図、同図(b)は同図(a)のA−A’線に沿った液晶表示装置の一部を示した断面図である。実施例1に係る表示装置40は、比較例2に係る表示装置11Aと同様な構成である。ただし、共通電極配線層14の分割位置のサブピクセル間と同じ色のサブピクセル間の金属配線層15はすべて配置しない。また、比較例2に係る表示装置11Aでは赤と緑のサブピクセル間で共通電極14を分割しているが、実施例1に係る表示装置40では赤と青のサブピクセル間で共通電極14を分割している。図6Aの場合は赤と青のサブピクセル間で共通電極14が分割されているため、すべての赤と青のサブピクセル間の金属配線層15は除去されている。ただし、図6Bは赤と緑のサブピクセル間で共通電極14が分割されて、すべての赤と緑のサブピクセル間の金属配線層15は除去されている場合の混色を示している。   FIG. 6A is a diagram illustrating the configuration of the liquid crystal display device according to the first embodiment. FIG. 6B is a diagram illustrating color mixing of the liquid crystal display device according to the first embodiment. FIG. 6A is a plan view showing a part of the liquid crystal display device, and FIG. 6B is a cross-sectional view showing a part of the liquid crystal display device along the line AA ′ in FIG. is there. The display device 40 according to the first embodiment has the same configuration as the display device 11A according to the second comparative example. However, not all the metal wiring layers 15 between the sub-pixels of the same color as the sub-pixels at the division position of the common electrode wiring layer 14 are arranged. Further, in the display device 11A according to the comparative example 2, the common electrode 14 is divided between the red and green subpixels. However, in the display device 40 according to the first embodiment, the common electrode 14 is formed between the red and blue subpixels. It is divided. In the case of FIG. 6A, since the common electrode 14 is divided between the red and blue subpixels, the metal wiring layer 15 between all the red and blue subpixels is removed. However, FIG. 6B shows the color mixture when the common electrode 14 is divided between the red and green subpixels and the metal wiring layer 15 between all the red and green subpixels is removed.

図6B(a)はCFガラス基板が右にずれた場合、同図(b)はCFガラス基板が左にずれた場合を示している。同図(ar)、(br)は液晶表示装置を右側から見た場合、同図(ac)、(bc)は液晶表示装置を正面から見た場合、同図(al)、(bl)は液晶表示装置を左側から見た場合を示している。同図(a1)、(b1)は赤サブピクセルのみに白電圧が印加された場合に組立ずれが起きたとき、同図(a2)、(b2)は緑サブピクセルのみに白電圧が印加された場合に組立ずれが起きたとき、同図(a3)、(b3)は青サブピクセルのみに白電圧が印加された場合に組立ずれが起きたときを示している。共通電極配線層14の分割位置、すなわち、金属配線層15がない箇所が比較例2よりも短い周期で配置されるので、同図(a2)(ar)に示すように緑色画面に赤色が少し一様に混じり、同図(b1)(bl)に示すように赤色画面に緑色が少し一様に混じる。実施例1に係る表示装置40では、すべての赤と青のサブピクセル間の金属配線層15は除去されているので、青色画面に赤色が少し一様に混じり、赤色画面に青色が少し一様に混じる。ただし、透過率が最も高い緑のサブピクセルの横の金属配線層15は除去されていないので、図6Bの場合よりも混色を防止することができる。   FIG. 6B (a) shows a case where the CF glass substrate is shifted to the right, and FIG. 6B shows a case where the CF glass substrate is shifted to the left. FIGS. 7A and 7B show the liquid crystal display device when viewed from the right side, FIGS. 5A and 5B show the liquid crystal display device when viewed from the front, and FIGS. The case where the liquid crystal display device is viewed from the left side is shown. (A1) and (b1) show that when a white voltage is applied only to the red sub-pixel and an assembly shift occurs, (a2) and (b2) show that the white voltage is applied only to the green sub-pixel. In the case where an assembly error occurs, FIGS. 3A and 3B show the case where an assembly error occurs when a white voltage is applied only to the blue subpixel. Since the division position of the common electrode wiring layer 14, that is, the portion where the metal wiring layer 15 is not provided is arranged with a cycle shorter than that of the comparative example 2, a little red is displayed on the green screen as shown in FIG. It is mixed uniformly, and green color is mixed a little uniformly on the red screen as shown in FIGS. In the display device 40 according to the first embodiment, since the metal wiring layer 15 between all the red and blue sub-pixels is removed, the red color is slightly mixed with the blue screen, and the blue color is slightly uniform with the red screen. Mixed with. However, since the horizontal metal wiring layer 15 of the green subpixel having the highest transmittance is not removed, color mixing can be prevented more than in the case of FIG. 6B.

本実施例の構成では赤と青のサブピクセル間では視野角混色防止効果が得られないが、緑と青、緑と赤のサブピクセル間では視野角混色防止効果を得ることができる。   In the configuration of this embodiment, a viewing angle color mixing prevention effect cannot be obtained between red and blue subpixels, but a viewing angle color mixing prevention effect can be obtained between green and blue subpixels.

タッチパネルの駆動電極配線層の機能を兼ねる共通電極配線層14はY方向に延在し、X方向に分割されて周期的に配置されており、検出電極配線層50はX方向に延在し、Y方向に複数配置されている。共通電極配線層14の幅は検出電極配線層50の幅よりも広い。検出電極配線層は共通電極配線層よりも容易に増加することができる。したがって、縦長の表示装置において、検出電極配線層を増加することによって、容易にタッチ検出精度を向上することができる。   The common electrode wiring layer 14 that also functions as a drive electrode wiring layer of the touch panel extends in the Y direction, is divided in the X direction and is periodically arranged, and the detection electrode wiring layer 50 extends in the X direction. A plurality are arranged in the Y direction. The width of the common electrode wiring layer 14 is wider than the width of the detection electrode wiring layer 50. The detection electrode wiring layer can be increased more easily than the common electrode wiring layer. Therefore, in a vertically long display device, touch detection accuracy can be easily improved by increasing the number of detection electrode wiring layers.

実施例2に係る液晶表示装置は、図2Aの比較例2に係る液晶表示装置11Aと同じ構成、すなわち、分割位置のみ金属配線層を排除し、それ以外のサブピクセル間は金属配線層15を配置する構成である。しかし、サブピクセルの精細度が十分であれば、面内であるサブピクセル間のみ視野角混色が生じたとしても、その領域の幅は人間の目にとって十分小さく認識できない。したがって、赤サブピクセルと緑サブピクセルとの間の混色防止効果を得ることができる。なお、赤と青のサブピクセル間で共通電極14を分割すれば、さらに混色を防止することができる。   The liquid crystal display device according to Example 2 has the same configuration as that of the liquid crystal display device 11A according to Comparative Example 2 in FIG. 2A, that is, the metal wiring layer is excluded only at the division positions, and the metal wiring layer 15 is provided between the other subpixels. It is the structure to arrange. However, if the definition of the subpixel is sufficient, even if viewing angle color mixing occurs only between the subpixels in the plane, the width of the region cannot be recognized sufficiently small for human eyes. Therefore, it is possible to obtain a color mixing prevention effect between the red subpixel and the green subpixel. If the common electrode 14 is divided between the red and blue subpixels, color mixing can be further prevented.

The liquid crystal display device 40A according to the third embodiment shows a configuration in which the division position of the common electrode wiring layer 14 is zigzag.

共通電極配線層14のソース配線層16方向(Y方向)の分割位置は、1行目L1は赤サブピクセルと緑サブピクセルの間、2行目L2は緑サブピクセルと青サブピクセルの間、3行目L3は青サブピクセルと赤サブピクセルの間、4行目L4は緑サブピクセルと青サブピクセルの間、5行目L5は赤サブピクセルと緑サブピクセルの間である。共通電極配線層14のゲート配線層方向(X方向)の分割位置は、1行目L1の緑サブピクセルと2行目L2の緑サブピクセルの間、2行目L2の青サブピクセルと3行目L3の青サブピクセルの間、3行目L3の青サブピクセルと4行目L4の青サブピクセルの間、4行目L4の緑サブピクセルと5行目L5の緑サブピクセルの間、である。分割領域20は、微視的には、X方向に2サブピクセルの幅でジクザグに配置され、巨視的には、Y方向に延在する。   The division position of the common electrode wiring layer 14 in the direction of the source wiring layer 16 (Y direction) is such that the first row L1 is between the red subpixel and the green subpixel, and the second row L2 is between the green subpixel and the blue subpixel. The third row L3 is between the blue and red subpixels, the fourth row L4 is between the green and blue subpixels, and the fifth row L5 is between the red and green subpixels. The division position of the common electrode wiring layer 14 in the gate wiring layer direction (X direction) is between the green subpixel of the first row L1 and the green subpixel of the second row L2, and the blue subpixel of the second row L2 and the third row. Between the blue subpixel of the eye L3, between the blue subpixel of the third row L3 and the blue subpixel of the fourth row L4, between the green subpixel of the fourth row L4 and the green subpixel of the fifth row L5. is there. Microscopically, the divided areas 20 are arranged in a zigzag manner with a width of 2 subpixels in the X direction, and macroscopically extend in the Y direction.

図7Aにおいて、1行目L1の緑サブピクセルの上および5行目L5の緑サブピクセルの下に共通電極配線層14のゲート配線層方向(X方向)の分割領域が記載されているが、1行目L1の赤サブピクセルの上および5行目L5の赤サブピクセルの下に共通電極配線層14のゲート配線層方向(X方向)の分割領域を設けてもよい。この場合は、分割領域20は、微視的には、X方向に4サブピクセルの幅でジクザグに配置され、巨視的には、Y方向に延在する。   In FIG. 7A, the divided region in the gate wiring layer direction (X direction) of the common electrode wiring layer 14 is described above the green subpixel of the first row L1 and below the green subpixel of the fifth row L5. A divided region in the gate wiring layer direction (X direction) of the common electrode wiring layer 14 may be provided above the red subpixel of the first row L1 and below the red subpixel of the fifth row L5. In this case, the divided regions 20 are microscopically arranged in a zigzag manner with a width of 4 subpixels in the X direction, and macroscopically extend in the Y direction.

図7B(a)はCFガラス基板が右にずれた場合、同図(b)はCFガラス基板が左にずれた場合を示している。同図(ar)、(br)は液晶表示装置を右側から見た場合、同図(ac)、(bc)は液晶表示装置を正面から見た場合、同図(al)、(bl)は液晶表示装置を左側から見た場合を示している。同図(a1)、(b1)は赤サブピクセルのみに白電圧が印加された場合に組立ずれが起きたとき、同図(a2)、(b2)は緑サブピクセルのみに白電圧が印加された場合に組立ずれが起きたとき、同図(a3)、(b3)は青サブピクセルのみに白電圧が印加された場合に組立ずれが起きたときを示している。実施例2で示した構成の精細度が十分でない場合(比較例2)、視野角混色が線状にみえる場合がある。その場合、本実施例のように分割位置をジグザグにすることで同図(a1)(ar)に示すように赤色画面に青色の縦筋が現れ、同図(a2)(ar)に示すように緑色画面に赤色の縦筋が現れ、同図(a3)(ar)に示すように青色画面に緑色の縦筋が現れる。また、同図(b1)(bl)に示すように赤色画面に緑色の縦筋が現れ、同図(b2)(bl)に示すように緑色画面に青色の縦筋が現れ、同図(b3)(bl)に示すように青色画面に赤色の縦筋が現れる。ただし、本実施例のように分割位置をジグザグにすることで視野角混色が生じた場合の光漏れ量を比較例2に比べて1/3にすることができる。したがって、視野角混色部分の視認性を比較例2よりも低下させることができる。   FIG. 7B (a) shows a case where the CF glass substrate is shifted to the right, and FIG. 7B shows a case where the CF glass substrate is shifted to the left.

In the case where an assembly error occurs, FIGS. 3A and 3B show the case where an assembly error occurs when a white voltage is applied only to the blue subpixel. When the definition of the configuration shown in Example 2 is not sufficient (Comparative Example 2), viewing angle color mixing may appear linear. In that case, as shown in this embodiment, when the dividing position is zigzag, blue vertical stripes appear on the red screen as shown in (a1) (ar) of the figure, and as shown in (a2) (ar) of the figure. The red vertical streaks appear on the green screen, and the green vertical streaks appear on the blue screen as shown in FIG. Further, as shown in FIGS. (B1) and (bl), green vertical stripes appear on the red screen, and as shown in FIGS. (B2) and (bl), blue vertical stripes appear on the green screen. ) As shown in (bl), red vertical stripes appear on the blue screen. However, the amount of light leakage when the viewing angle color mixture occurs can be reduced to 1/3 compared to the comparative example 2 by making the divided position zigzag as in the present embodiment. Therefore, the visibility of the viewing angle mixed color portion can be reduced as compared with Comparative Example 2.

(A1) and (b1) show that when a white voltage is applied only to the red sub-pixel and an assembly shift occurs, (a2) and (b2) show that the white voltage is applied only to the green sub-pixel. In the case where an assembly error occurs, FIGS. 3A and 3B show the case where an assembly error occurs when a white voltage is applied only to the blue subpixel. Blue vertical stripes appear on the red screen as shown in (a1) and (ar) of the figure, and red vertical stripes appear on the blue screen as shown in (b3) and (bl) of the figure. However, the amount of light leakage when the viewing angle color mixture occurs can be halved compared to the comparative example 2 by zigzag the division position as in this embodiment. Therefore, the visibility of the viewing angle mixed color portion can be reduced as compared with Comparative Example 2.

共有電極配線層14の分割位置は、もし光が漏れてもその透過光がすくなく、混色として認識しにくくてすむように赤サブピクセルと青サブピクセル間での分割が望ましい。しかしながら、RGBWの4色サブピクセルで青サブピクセルと白サブピクセルが同一ソース配線層16を共用する画素構成の場合、赤サブピクセルと青サブピクセル間で直線状に分割しようとした場合、透過率の高い白サブピクセル横が含まれてしまう。緑サブピクセルよりも透過率の高い白サブピクセルの横で共有電極配線層14を分割した場合、もし光が漏れた場合の視野角混色が顕著になってしまう。そこで、白サブピクセルを回避するように赤サブピクセルと青サブピクセルとの間をジグザグに分割することで、視野角混色を低減することができる。なお、比較例2と同様に共有電極配線層14を直線状に分割する場合は、白サブピクセルの横を避けるために、比較例2と同様に赤サブピクセルと緑サブピクセルの間で共有電極配線層14を分割するのが好ましい。   It is desirable that the shared electrode wiring layer 14 is divided between the red subpixel and the blue subpixel so that the transmitted light does not flow even if light leaks, and it is difficult to recognize the mixed color. However, in the case of a pixel configuration in which the blue subpixel and the white subpixel share the same source wiring layer 16 in the RGBW four-color subpixels, if the red subpixel and the blue subpixel are divided linearly, the transmittance High white subpixel width is included. If the shared electrode wiring layer 14 is divided beside the white subpixel having a higher transmittance than the green subpixel, the color mixing of the viewing angles becomes significant if light leaks. Therefore, by dividing the red subpixel and the blue subpixel in a zigzag manner so as to avoid the white subpixel, the viewing angle color mixture can be reduced. When the shared electrode wiring layer 14 is divided linearly as in the comparative example 2, in order to avoid the side of the white subpixel, the shared electrode is arranged between the red subpixel and the green subpixel as in the comparative example 2. The wiring layer 14 is preferably divided.
