Abstract

A method for manufacturing a liquid crystal display device includes a step (A) of preparing an active matrix substrate, a step (B) of preparing a counter substrate, and a step (C) of producing a liquid crystal display panel using the prepared active matrix substrate and counter substrate. The step (C) includes a step (C) of bonding the active matrix substrate with the counter substrate with a predetermined gap interposed therebetween and a step (C) of forming a liquid crystal layer before or after the step (C). An alignment film is an alignment film having a specific resistance of 1×10Ω·cm or greater when a backlight is illuminated. The step (C) further includes, after the steps (C) and (C), a step (C) of irradiating the active matrix substrate, the liquid crystal layer, and the counter substrate with ultraviolet light.
