Abstract:
A transflective liquid crystal display device provided with columnar spacers is provided that can suppress variation in color tone of white in a reflective mode and can minimize degradation in reflectivity even when a coloring material used for a transmissive region and a coloring material used for a reflective region are the same. The device includes a color filter substrate, a TFT substrate, a liquid crystal material sandwiched by the color filter substrate and the TFT substrate, columnar spacers formed only in pixels having a green coloring material and defining a cell gap, and light-blocking portions provided only in predetermined regions in the vicinity of locations where the columnar spacers are formed.
