LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A liquid-crystal display device is provided to realize a high-quality and high-reliability screen display, and to be capable of controlling image-sticking and display blur. CONSTITUTION: A liquid-crystal display comprises an array substrate, a counter substrate facing the array substrate, and a liquid crystal sealed between the two substrates. The liquid-crystal display includes sub-pixel portions respectively having a switching device arranged like a matrix, the sub-pixel portion is provided with a pixel electrode wiring and a common electrode wiring for applying an electric field to the liquid crystal and an lignment film for controlling an alignment direction of the liquid crystal; a pixel potential is supplied to the pixel electrode wiring through the switching device; a common potential is supplied to the common electrode wiring; and the alignment film is insulated from the pixel electrode wiring and electrically connected to the common electrode wiring.
