Abstract
The present invention provides a transflective liquid crystal device in which color display can be made uniform over the display surface in both the reflective display mode and the transmissive display mode. The liquid crystal device can include a pair of substrates which sandwich liquid crystal, a light reflecting film formed on the substrate, and a color filter formed on the light reflecting film. The color filter can include a partitioning member, which divides the surface of the substrate into a plurality of sections, and subpixels which are individually formed in the sections. The light reflecting film is provided with openings formed at regions corresponding to the thickest parts of the subpixels, openings formed at regions corresponding to central parts of the section, openings which extend in longitudinal direction of the rectangular sections, or openings formed in the shape corresponding to the thickness distribution of the subpixels.
