Abstract
There is disclosed a transflective liquid crystal display having pixels each including a reflective region and a transmissive region. The aperture ratio of the pixels can be enhanced. End portions of two adjacent color filters are overlapped to form an optically shielding portion for each pixel. The optically shielding portion and the reflective region cooperate to form an optically shielding film acting as a black matrix for the transmissive region. The aperture ratio is enhanced by improving the positional relationship between the reflective regions and the color filters.
Claims9
A liquid crystal display device comprising:
- a plurality of pixels arranged in a matrix, each of the pixels including a reflective region;
- a color filter disposed opposite to the pixel;
- and
- optically shielding portions formed by overlaps between adjacent ones of the color filters;
- wherein said optically shielding portions have end portions overlapped on end portions of the reflective regions.
A liquid crystal display device comprising:
- a plurality of pixels arranged in a matrix, each of the pixel including a transparent electrode and a metal electrode;
- a switching element electrically connected with the transparent electrode and metal electrode of the pixel;
- a plurality of scanning signal lines for supplying control signal for controlling the switching element;
- a plurality of video signal lines for supplying video signal to the transparent electrode and metal electrode via the switching element;
- and
- a colored resin located opposite to the pixel electrode and having end portions adjacent to each other;
- wherein the metal electrode in each of the pixels is formed around the transparent electrode;
- wherein said end portions of the colored resin adjacent to each other overlap each other, forming optically shielding portions;
- and
- wherein the optically shielding portions have outer peripheral portions overlapped on outer peripheral portions of the metal electrodes.
A liquid crystal display device comprising:
- a plurality of delta arranged pixels, each of the pixels including a reflective electrode and a transparent electrode;
- switching element electrically connected with the reflective electrode and transparent electrode of the pixel;
- a plurality of scanning signal lines for supplying control signal for controlling said switching element;
- a plurality of video signal lines for supplying video signal to the reflective electrode and transparent electrode via said switching element;
- and
- a plurality of color filters disposed in a corresponding manner to said pixels, each of the color filters having hexagons of colored resin;
- wherein said reflective electrode in each pixel surrounds an outer periphery of the transparent electrode;
- wherein end portions of adjacent ones of the hexagons of the colored resin are overlapped to thereby form optically shielding portions;
- and
- wherein the optically shielding portions have outer peripheral portions overlapped on outer peripheral portions of the reflective electrodes of the pixels.
