Abstract:
The present invention regarding a liquid crystal display device aims to further prevent generation of low-temperature bubbles in a uniform cell gap and to further improve strength against pressure applied to a glass surface while saving a production cost. A liquid crystal display device according to the present invention includes multiple spacers arranged on a liquid crystal layer side of an array substrate. The multiple spacers include: a first spacer arranged in a part of an insulating layer having no contact hole formed thereon; and a second spacer arranged inside of the contact hole. The contact hole is provided on the insulating layer and connects a switching element to either a corresponding pixel electrode or a corresponding auxiliary capacitive layer.
