Definitions
- the present invention relates to a display device.
- a liquid crystal panel which is a main component constituting a liquid crystal display device has the following configuration. That is, the liquid crystal panel seals the liquid crystal by sandwiching the liquid crystal between the pair of transparent substrates and forming a seal portion around the liquid crystal. On one transparent substrate of the pair of transparent substrates, TFTs that are switching elements, pixel electrodes, and signal wirings are formed. On the other transparent substrate, a color filter, a common electrode, In addition, a black matrix or the like is formed.
- the liquid crystal panel having such a structure can display an image by being supplied with illumination light from a backlight device arranged on the back side. There is a problem that light from the backlight device leaks because a black matrix is not formed in.
- Patent Document 1 describes a configuration in which a black matrix is not arranged in the vicinity of the seal portion, and a light shielding layer made of a metal layer is arranged in the vicinity of the seal portion on the liquid crystal side surface of one transparent substrate.
- the light shielding layer shields the vicinity of the seal portion to prevent leakage of illumination light from the backlight device.
- Patent Document 1 (Problems to be solved by the invention)
- a light shielding layer made of a metal layer is added for light shielding, there is a possibility that the light shielding layer forms a parasitic capacitance with respect to other wirings and the like. Therefore, it is conceivable to secure the light shielding property in the vicinity of the seal portion by forming the black matrix in the vicinity of the seal portion instead of the light shielding layer made of the metal layer.
- the black matrix has a higher light shielding performance as its thickness is increased, there are concerns that the flatness deteriorates and a cell gap defect occurs.
- the light shielding performance increases as the concentration of the light shielding material contained in the black matrix increases, for example, a photosensitive resin material is contained in the black matrix and the black matrix is patterned by a photolithography method.
- concentration of the light-shielding material becomes too high, the sensitivity of the photosensitive resin material is lowered, which causes a problem that it is difficult to form a black matrix.
- the thickness of the black matrix and the concentration of the light-shielding material may not be sufficiently secured. In such a case, the light-shielding performance becomes insufficient and light can easily pass through the black matrix.
- the wiring superimposed on the black matrix described above includes, for example, a signal wiring connection wiring portion connected to each signal wiring and a common electrode connection wiring portion connected to a common electrode
- the common electrode connection wiring part is arranged as a solid pattern, so that the transmitted light of the black matrix is transmitted to the signal wiring connection wiring Part of the part is transparent, but the common electrode connection and wiring part is hardly transmitted.

- the wide wiring portion is formed as a solid pattern having no opening, light is hardly transmitted through the wide wiring portion, and between the narrow wiring portion and the narrow wiring portion.
- the ratio of the area of the wide wiring portion to the area of the opening is a ratio of the area of the narrow wiring portion to the area of the opening portion between the adjacent narrow wiring portions. It is formed so as to be almost equal. In this way, the amount of light shielded by the wide wiring portion is equal to the amount of light shielded by the plurality of narrow wiring portions, and the amount of light transmitted through the opening of the wide wiring portion and the adjacent narrow wiring Since the amount of light transmitted through the opening portion between the two portions becomes equal, the wide wiring portion and the narrow wiring portion are easily seen equally by the user of the display device, thereby further improving the appearance.

Abstract
Description
上記した特許文献1では、遮光のために金属層からなる遮光層を追加しているため、遮光層が他の配線などに対して寄生容量を形成する、という問題が生じるおそれがある。そこで、金属層からなる遮光層に代えてブラックマトリクスをシール部の付近にまで拡張して形成することで、シール部の付近における遮光性を確保することが考えられる。ここで、ブラックマトリクスは、その厚さを増すほど遮光性能が高くなるものの、そうすると平坦性が悪化したりセルギャップ不良が発生する、などの問題が懸念される。それ以外にも、上記ブラックマトリクスに含有させる遮光性材料の濃度を高めるほど遮光性能が高くなるものの、例えばブラックマトリクスに感光性樹脂材料を含有させていてフォトリソグラフィ法によりブラックマトリクスをパターニングしていた場合には、遮光性材料の濃度が高くなり過ぎると、感光性樹脂材料の感度が低下してしまい、ブラックマトリクスの形成が困難になるという問題が生じる。このような事情から、上記ブラックマトリクスの厚さや遮光性材料の濃度を十分に確保できなくなる場合があり、そうなると遮光性能が不十分となってブラックマトリクスを光が透過し易くなることで、ブラックマトリクスと重畳する位置に配置されていた配線などが使用者に影として見えてしまって外観が悪化する、といった事態が発生することが懸念される。特に、液晶に電圧が印加されないときに光の透過率が最大となるノーマリホワイトモードの液晶パネルにおいては、シール部の付近では画素電極が存在しないために液晶における光の透過率が常に最大となっていて光漏れが発生し易く、上記のような影が視認されて外観が悪化することが懸念されていた。
本発明の第1の表示装置は、画像を表示可能な表示部と、前記表示部外の非表示部と、少なくとも前記非表示部に配されて光を遮る遮光部と、前記非表示部において複数が間欠的に並列する形で配される幅狭配線部と、前記非表示部に配されて前記幅狭配線部に比べて線幅が広く且つ部分的に開口部が形成されてなる幅広配線部と、を備える表示装置。
(1)前記幅広配線部は、その面積と前記開口部の面積との比率が、前記幅狭配線部の面積と隣り合う前記幅狭配線部の間に有される開口部位における面積との比率とほぼ等しくなるよう形成されている。このようにすれば、幅広配線部により遮光される光量と、複数の幅狭配線部により遮光される光量とが等しくなるとともに、幅広配線部の開口部を透過する光量と、隣り合う幅狭配線部の間に有される開口部位を透過する光量とが等しくなるので、当該表示装置の使用者には幅広配線部と幅狭配線部とが同等に見え易くなり、もって外観の改善に一層有効となる。
(11)前記表示部と前記非表示部とに区分されている一対の基板と、前記一対の基板間に挟持される液晶層と、前記一対の基板における前記液晶層側の板面に形成されて少なくとも前記表示部に配されるとともに前記液晶層に含まれる液晶分子を配向する一対の配向膜と、を備えており、前記一対の基板間に電圧が印加されない状態で光の透過率が最大となるノーマリホワイトモードとされる。このようにすれば、当該表示装置がノーマリホワイトモードとされると、一対の基板間に電圧が印加されない状態で光の透過率が最大となるため、常に光漏れに伴う外観の悪化が懸念されるものの、幅広配線部に形成された開口部、または隣り合う幅狭配線部の間を透過する光が漏れ出しても幅広配線部または幅狭配線部が影として使用者に視認され難くなり、もって外観の悪化が抑制される。
(1)前記一対の基板における前記液晶層側の板面に形成されて少なくとも前記表示部に配される一対の配向膜を備えており、前記液晶配向部は、前記一対の配向膜における前記表示部に配される部分により構成されているのに対し、前記一対の基板の少なくともいずれか一方における前記液晶層側の板面に、前記一対の配向膜の少なくともいずれか一方が前記配線部と平面に視て非重畳となる範囲に選択的に配されることで前記配向膜の配置されない配向膜非配置領域が有されていて、前記液晶非配向部は、前記配向膜非配置領域からなる。このようにすれば、液晶非配向部が配向膜の配置されない配向膜非配置領域からなることで、光の透過を一層好適に抑制することができる。また、配向膜の形成範囲に係る位置精度を十分確保できる場合に好適となる。
本発明によれば、外観を改善することができる。

本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれる。
(1)上記した各実施形態(実施形態3から実施形態6を除く)では、共通電極接続配線部に形成される開口部の幅寸法と、区分共通電極接続配線部の線幅とが同一とされたものを示したが、開口部の幅寸法と、区分共通電極接続配線部の線幅とが異なる構成、つまり開口部の幅寸法が区分共通電極接続配線部の線幅よりも大きい構成、または開口部の幅寸法が区分共通電極接続配線部の線幅よりも小さい構成を採ることも可能である。その場合でも、開口部の幅寸法は、区分共通電極接続配線部の線幅の1/3以上の大きさとされるのが好ましい。また、共通電極接続配線部に形成される開口部の幅寸法が2種類以上設定される構成としたり、区分共通電極接続配線部の線幅が2種類以上設定される構成とすることも可能である。
また、多結晶化されたシリコン薄膜の一種であるCGシリコン(Continuous Grain Silicon)薄膜からなる半導体膜を用いることも可能である。CGシリコン薄膜は、例えばアモルファスシリコン薄膜に金属材料を添加し、550℃以下程度の低温で短時間の熱処理を行うことで形成されており、それによりシリコン結晶の結晶粒界における原子配列に連続性を有している。CGシリコン薄膜は、アモルファスシリコン薄膜などに比べると、電子移動度が例えば200~300cm2/Vs程度と高くなっているので、TFTを容易に小型化して画素電極の透過光量を極大化することができ、もって高精細化及び低消費電力化を図る上で好適とされる。このような半導体膜を有するTFTは、半導体膜が最下層に配され、その上層側に絶縁膜を介してゲート電極が積層されてなる、スタガ型(コプレーナ型)とされている。
