Abstract:
The present invention provides a liquid crystal display device that maintains a sufficient voltage holding ratio over a long period of time even when a liquid crystal panel having a narrower frame is used and that undergoes no burn-in or no stains on a display screen. The liquid crystal display device of the present invention includes an active-matrix liquid crystal panel and a backlight, wherein the liquid crystal panel includes a liquid crystal layer, a pair of substrates between which the liquid crystal layer is sandwiched, alignment layers disposed on surfaces of the pair of substrates facing the liquid crystal layer, and a seal part that bonds the pair of substrates to each other and that is disposed around the liquid crystal layer, and the liquid crystal panel is formed by a liquid crystal one-drop fill process, wherein the liquid crystal layer includes a liquid crystal material and at least one of a radical scavenger and an antioxidant, and the seal part has a width of 0.6 mm or less at least in part.
