Disclosure of the Invention
[Problems to be solved by the invention]
However, in this liquid crystal device, since light is colored by a birefringence effect and an analyzing action, there is a problem that color reproducibility is poor.
【００１１】
【課題を解決するための手段】
まず、上記第１の目的を達成するための液晶装置に適用すべく、本発明の液晶装置は、透明性を有する第１および第２の基板と、前記第１および第２の基板間に挟持された液晶層と、前記第１の基板における前記液晶層側の面に形成された透明電極と、前記第２の基板における前記液晶層側の面に形成された反射層と、当該反射層の上面に形成された着色層とを具備する液晶装置であって、前記反射層と前記着色層との間には、形成された前記反射層の領域を覆うように保護膜が形成されてなり、当該保護膜によって前記反射層と前記着色層は隔てられていることを特徴とする。[0011]
[Means for Solving the Problems]
First, in order to apply to a liquid crystal device for achieving the first object, the liquid crystal device of the present invention comprises first and second substrates having transparency, and the first and second substrates held between the first and second substrates. Liquid crystal layer, a transparent electrode formed on the surface of the first substrate on the liquid crystal layer side, a reflective layer formed on the surface of the second substrate on the liquid crystal layer side, and the reflective layer A liquid crystal device comprising a colored layer formed on the upper surface, wherein a protective film is formed between the reflective layer and the colored layer so as to cover an area of the formed reflective layer. The reflective layer and the colored layer are separated by the protective film.
【００１２】
本発明によれば、金属膜と着色層とが保護膜によって隔てられているので、着色層を形成する際に金属膜表面が劣化しない。そのため金属膜の反射特性が良好な半透過反射型または反射型の液晶装置が実現する。[0012]
According to the present invention, since the metal film and the colored layer are separated by the protective film, the surface of the metal film does not deteriorate when the colored layer is formed. Therefore, a semi-transmissive reflective or reflective liquid crystal device having a good reflection characteristic of the metal film is realized.
【００１４】
また、本発明の液晶装置は、前記保護膜は、前記反射層の酸化膜を含むものであって、前記保護膜の屈折率は、前記反射層の酸化膜の屈折率より小さいことを特徴とする。
保護膜の他例としては前記金属の酸化物以外の酸化物、有機絶縁膜又は窒化物を用いることができる。前記金属の酸化物以外の酸化物としてはＳｉＯ２等の酸化シリコン、前記有機絶縁膜としてはアクリル樹脂、窒化物としてはＳｉ３Ｎ４に代表される窒化シリコンが上げられる。金属膜材料の酸化物以外の酸化物を保護膜として用いた場合にあっては、屈折率が小さいことにより反射率の低下が抑えられる、有機絶縁膜を用いた場合には、スピンコート、ロールコート等により容易に保護膜を形成できる、窒化物を用いる場合には、屈折率が小さいことにより反射率の低下が抑えられるという利点がある。[0014]
The liquid crystal device according to the present invention is characterized in that the protective film includes the oxide film of the reflective layer, and the refractive index of the protective film is smaller than the refractive index of the oxide film of the reflective layer. Do.
As another example of the protective film, an oxide other than the metal oxide, an organic insulating film, or a nitride can be used. Examples of oxides other than the metal oxides include silicon oxides such as SiO 2 , acrylic resins as the organic insulating film, and silicon nitride represented by Si 3 N 4 as nitrides. In the case where an oxide other than the oxide of the metal film material is used as a protective film, a decrease in reflectance can be suppressed because the refractive index is small. When a protective film can be easily formed by coating or the like, and nitride is used, there is an advantage that the decrease in reflectance can be suppressed because the refractive index is small.
【００１５】
また、本発明の液晶装置は、前記保護膜は、複数の絶縁膜が重ね合わされた多層膜であることを特徴とする。
ここで前記多層膜は、上記した金属酸化膜、それ以外の酸化膜、有機絶縁膜及び窒化膜から選ばれる２種以上の膜を適宜組み合わせて保護膜としてもよい。[0015]
Further, in the liquid crystal device according to the present invention, the protective film is a multilayer film in which a plurality of insulating films are stacked.
Here, the multilayer film may be a protective film by appropriately combining two or more films selected from the above-described metal oxide film, other oxide films, organic insulating films, and nitride films.
