Liquid crystal display device

A liquid crystal display device comprising:

• a substantially rectangular optical switching member in which a first polarizer, a first substrate, a second substrate, and a second polarizer are sequentially provided from a front surface side;
• a frame which surrounds the optical switching member;
• a planar light source which is disposed on the rear surface side of the optical switching member;
• at least one optical sheet group which is disposed at the front surface of the planar light source;
• and
• an adhesive layer which fixes the optical switching member, the frame, and the optical sheet group to each other, and has a substantially rectangular opening,
• wherein a surface at least one side of an optical sheet included in the optical sheet group and located at the frontmost surface of the optical sheet group is adhered to the adhesive layer, and at least one other side of the frontmost surface of the optical sheet is located inside the opening of the adhesive layer so as not to be adhered to the adhesive layer.
