Liquid crystal display device

摘要

A liquid crystal display device (100) includes: a pair of substrates (101,102) opposing each other; a liquid crystal layer (110) interposed between the pair of substrates; a plurality of switching elements (201) arranged in a matrix pattern on one of the pair of substrates; gate signal lines for supplying gate signals for driving the switching elements; source signal lines crossing the gate signal lines for supplying display signals to the switching elements; an interlayer insulating film (104) provided on one of the pair of substrates over the gate signal lines and the source signal lines; and pixel electrodes (202) provided over the gate signal lines and the source signal lines via the interlayer insulating film. The interlayer insulating film on one of the pair of substrates extends to a surrounding region of a display pixel area. An electrode pattern (105) for adsorbing an ionic impurity is provided on the interlayer insulating film in the surrounding region. The pixel electrodes and the electrode pattern can be reflective electrodes.
