Abstract

See full text

A color liquid crystal display device includes a first substrate having a surface on which a transparent electrode and a first aligning film covering the transparent electrode are arranged, a second substrate having an electrode arranged to oppose the first substrate, and a second aligning film covering the electrode, the electrode having a plurality of pixels formed on its inner surface, and the pixels being formed in an area opposing the transparent electrode, a liquid crystal layer sandwiched between the first and second substrates and having an initial aligned state in which liquid crystal molecules are aligned in a predetermined direction by the first and second aligning films, a polarizing member arranged outside the first substrate such that the polarization axis of the polarizing member crosses an aligning direction of liquid crystal molecules adjacent to the first aligning film at an angle other than a right angle, and a reflecting member, arranged on the second substrate side, for reflecting light which is incident from the polarizing member on the first substrate side and transmitted through the liquid crystal layer. Active elements formed in correspondence with the plurality of pixel electrodes and respectively connected thereto, and compensation capacitor means, connected to the active elements to be parallel with the pixel electrodes, for compensating for variations in voltages applied between the pixel electrodes and the counter electrode are arranged on the inner surface of the first or second substrate.
