  • Patent number: 7656465
    Abstract: Fine electrode patterns pattern-formed in the shape of fine teeth of a comb bilaterally symmetrical with respect to band-shaped portions are formed at even intervals in a pixel electrode, and band-shaped dielectric layers are pattern-formed at even intervals to cover the fine electrode patterns in a display pixel. By the existence of the dielectric layer and the fine electrode patterns complementing this, a portion formed with this layer and the fine electrode patterns is a high threshold voltage region, and relatively, a low threshold voltage region where the dielectric layer does not exist is formed. By the aforementioned construction, it becomes possible to improve a delay in response speed at low gray levels and increase the speed of halftone response, whereby a very reliable image display having moving image performance almost equal to that of a CRT is realized.
