Abstract
A transflective liquid crystal display device can obtain a high luminance and a high contrast to realize a superior color repeatability and improve an image quality in a color display. In a second substrate, a region facing a region where a light reflection portion is formed includes a first region where a color filter layer is formed at a predetermined layer thickness and a second region where the color filer layer is not formed, and, in a first substrate, a layer thickness difference adjustment layer for adjusting a difference of a layer thickness of the liquid crystal layer generated by a height of step between the first region and the second region due to the color filter layer is formed in the region where the light reflection portion is formed so as to face the second region.
