摘要： A liquid crystal panel (2) includes scanning signal lines (31) for supplying scanning signals to gate electrodes (20) of TFTs (14), and data signal lines (32) for supplying data signals to data electrodes (24) of TFTs. The liquid crystal panel further includes auxiliary capacitive electrode pads (27a) for use in forming auxiliary capacitance and an auxiliary capacitive lines (33) so as not to generate a capacitive bond with the scanning signal lines. The liquid crystal panel is driven at a rewriting frequency of a screen of not more than 30 Hz. As a result, the liquid crystal panel can be driven at a low consumption power while maintaining a desirable display quality of the liquid crystal panel.

摘要： The present invention provides a transflective liquid crystal display device which is produced by a simple process with minimum increase in the production cost and which achieves both high-quality reflective display and transmissive display. The present invention relates to a vertical alignment transflective liquid crystal display device for transmissive display and reflective display. The display device includes: a back-side polarizer; a liquid crystal cell; a viewing-side polarizer; a first retardation layer; and a second retardation layer. The liquid crystal cell includes a pair of substrates and a liquid crystal layer disposed between the pair of substrates. The viewing-side polarizer has an absorption axis orthogonal to an absorption axis of the back-side polarizer. The first retardation layer is disposed between the liquid crystal layer and the viewing-side polarizer at a transmissive display region and a reflective display region, satisfies 1.5 ≤ Nz ≤ 9.0, has an in-plane slow axis orthogonal to the absorption axis of the viewing-side polarizer, and satisfies 20 nm ≤ Re(550) ≤ 80 nm. The second retardation layer is disposed between the first retardation layer and the viewing-side polarizer at the reflective display region, and converts linearly polarized light incident from the viewing-side polarizer into circularly polarized light together with the first retardation layer when no voltage is applied.
