摘要： The present invention provides a method for producing a substrate for a liquid crystal display panel and a photomask each of which can suppress misalignment of liquid crystal molecules due to liquid crystal alignment control projections. The present invention relates to a method for producing a substrate for a liquid crystal display panel. The substrate includes liquid crystal alignment control projections, and the liquid crystal alignment control projections include a main projection and a sub-projection. The sub-projection is linear and is lower than the main projection. The production method includes a step of forming a positive photosensitive resin film and a step of exposing the photosensitive resin film to light through a photomask. The photomask has a light-control region for forming the sub-projection. The light-control region has a slit-shaped translucent part.

摘要： An object of the present invention iso attain switching at a high contrast ratio and a high light utilization factor. Incident light from a second surface of a prism is not reflected by the surface of a transmission substrate but guided to refractive index substance layers. The incident light is split into light reflected by the interface between the refractive index substance layers and light passing through the interface in accordance with the relationship between the refractive indices of the refractive index substance layers. The transmitted light is reflected by the surface of a reflecting electrode tilted by angle .delta. with respect to the surface of an insulating substrate. The light reflected by the interface goes out in a direction different from the direction of the light reflected by the surface of the reflecting electrode. The light intensities of the reflected light and the transmitted light at the interface can be controlled by applying a voltage across the reflecting electrode and the transparent electrode and by changing the refractive index of the variable refractive index substance layer.
摘要翻译：本发明的目的是在高对比度和高光照率下进行切换。来自棱镜的第二表面的入射光不被透射基板的表面反射，而是被引导至折射率物质层。根据折射率物质层的折射率之间的关系，将入射光分为由折射率物质层与通过界面的光之间的界面反射的光。透射光被相对于绝缘基板的表面倾斜角度的反射电极的表面反射。由界面反射的光沿与反射电极的表面反射的光的方向不同的方向离开。可以通过在反射电极和透明电极两端施加电压并通过改变可变折射率物质层的折射率来控制反射光的光强度和界面处的透射光。

摘要： A dry film resist is used to form an interlayer insulating film in a process for fabricating a liquid crystal display device of the POP structure. The dry film resist is formed by applying a photosensitive resin on a base film to a uniform thickness, and a protective film layer is formed on a surface of the photosensitive resin film thus formed. From the dry film resist guided to the vicinity of a glass substrate, the protective film is removed immediately before transfer. Then, the photosensitive resin is heated and pressed against the foregoing glass substrate by a transfer roller, whereby the interlayer insulating film is formed.
