Abstract

Disclosed herein is a display apparatus including a first substrate patterned to create pixel electrodes, a second substrate placed to face the first substrate and a liquid-crystal layer sandwiched by the first and second substrates wherein: one of the first and second substrates is patterned to create color filters each provided for one of a plurality of different colors as color filters each associated with one of the pixel electrodes each included in one of pixels each provided for one of the different colors; each of the pixels each provided for one of the different colors has a pixel area which varies from color to color; and the ratio of the electrode area of any particular one of the pixel electrodes to the pixel area of the pixel that includes the particular pixel electrode varies from color to color.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] The present application contains subject matter related to Japanese Patent Application JP 2007-283160 filed in the Japan Patent Office on Oct. 31, 2007, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention generally relates to display devices. Specifically, the present invention relates to a display device for driving liquid crystal molecules in FFS (Fringe Field Switching) mode. Background technique [0004] In the field of liquid crystal display devices operating in a horizontal electric field mode, attention is being paid to a liquid crystal mode for realizing a wide viewing angle and high contrast ratio. In particular, the FFS mode improves the aperture ratio and light transmittance compared to the IPS (In-Plane Switching) mode. [0005] FIG. 12 is a plurality of views respectively showing a general liquid crystal display device operating in the FFS mode. ...
