Patent ID: 7864284

Claim:
A transflective liquid crystal display device, comprising: a first substrate having a light-blocking film and a color filter in which red, green, and blue coloring materials form respective pixels; a second substrate having a transmissive pixel electrode that forms transmissive regions within said pixels, a reflective pixel electrode that forms reflective regions within said pixels, and wiring lines for supplying a control signal and a signal applied to said transmissive pixel electrode and said reflective pixel electrode; a liquid crystal material sandwiched by said first substrate and said second substrate; and columnar spacers formed in said reflective regions having said green coloring material, and defining a gap between said first substrate and said second substrate, no columnar spacers being formed in the regions having said red and said blue coloring material, wherein said first substrate further has light-blocking portions formed in the same layer as said light-blocking film in a region surrounding said columnar spacers and only in said reflective regions of said pixels having said green coloring material, said light-blocking portions increasing the area of said light-blocking film so that said reflective regions of said blue coloring material and said red coloring material are equal and said reflective region of green coloring material is smaller than said reflective region of said blue coloring material and of said red coloring material, and in said reflection region of each pixel defined by the light blocking film, said blue coloring material, said red coloring material and said green coloring material do not have an opening and a notch.
