Abstract
A face plate on which a frame is formed for improved design aesthetics is bonded to a top surface of an upper polarizer of a liquid crystal display panel with a pressure-sensitive adhesive material. The frame on the face plate is formed from five layers of printing. The pressure-sensitive adhesive material has a three-layer structure having a first pressure-sensitive adhesive member, a base material, and a second pressure-sensitive adhesive member. The first pressure-sensitive adhesive member is formed thicker than the second pressure-sensitive adhesive member, and hence the pressure-sensitive adhesive material can maintain a necessary thickness above the frame formed on the face plate. The reliability of adhesion between the face plate and the liquid crystal display panel is thus improved.
