发明名称 LIQUID CRYSTAL DISPLAY DEVICE
摘要 PROBLEM TO BE SOLVED: To improve the decline of a resolution due to blotting or the like, to reduce the loss of light and to perform bright display with less visual dependency by providing a color filter layer with a filter base material and the particle of a light refractive index different from it. SOLUTION: The red, green and blue color filter layers 3-5 of an opposite substrate 200 are composed of the respective filter base materials 31-33 and fine balls 51-53 dispersed in them and the fine balls 51-53 are provided with the refractive index different from the filter base materials 31-33. The filter base materials 31-33 are provided with the action of filtering and the fine balls 51-53 are provided with a lens action. When light made to pass through a liquid crystal layer 300 passes through the fine balls 51-53, an optical path is changed by the lens effect and the light is diffused as a result. Since the lens effect of refracting the light by the fine balls 51-53 is utilized a scattering effect by diffusion is not generated, the deflection state of the light is not disturbed at the time of passing through the color filter layer and the problem of disturbing the deflection state of the light and lowering image quality is not generated.
