Abstract

Provided is a display device capable of preventing, in a case where a flexible printed circuit board is bent to be fixed to a support portion of the display device, a troublesome phenomenon due to a force generated in the flexible printed circuit board by recovery from deformation, that is, spring-back. The display device includes the flexible printed circuit board, and the flexible printed circuit board is disposed in a bent state, and has at least a hole formed therein. The flexible printed circuit board is fixed to a support member (for example, backlight back surface plate, frame, etc.) included in the display device by a first fixation member (for example, double-sided pressure sensitive adhesive tape) and further is fixed to the support member by a second fixation member (for example, pin) through the hole.

Claims (8)

1. A display device, comprising:

a support member;

a flexible printed circuit board which is supported by the support member in a bent state and which has at least one of a through hole and a slit formed therein;

a first fixing member which fixes the flexible printed circuit board to the support member; and

a second fixing member which is fixed to the first fixing member through the at least one of the through hole and the slit,

wherein the first fixing member is formed by at least one adhesive material selected from a group consisting of a resin adhesive, a hot melt adhesive, and a pressure sensitive adhesive,

wherein the support member has a hole on a surface that faces a same side as a front side of the display device, and

wherein the second fixing member comprises a pin fitting into the hole.
