Abstract

A display module ESD resistance of which is improved is achieved. In a display module (1) that includes: a display panel (10); a flexible printed circuit board (20) that is connected to the display panel (10); and a circuit board (30) that supplies a drive signal to the display panel (10) via the flexible printed circuit board (20), the flexible printed circuit board (20) includes an exposed portion (28), in which a conductive portion (24) connected to a ground is exposed, on a rear surface side of a connection surface (27) to the display panel (10).

Claims

1. A display module comprising:

a display panel;

a flexible printed circuit board that is connected to the display panel; and

a circuit board that supplies a drive signal to the display panel via the flexible printed circuit board, wherein

the flexible printed circuit board includes an exposed portion, in which a conductive portion connected to a ground is exposed, on a rear surface side of a connection surface to the display panel.

2. The display module according to claim 1, wherein the conductive portion is electrically connected to a ground of a case through the circuit board.

3. The display module according to claim 1, wherein the exposed portion is formed to be wider than the connection surface by which the flexible printed circuit board is connected to the display panel.

4. The display module according to claim 1, wherein the conductive portion is exposed in the exposed portion via a plurality of openings that are formed in a cover layer which covers the conductive portion.

5. The display module according to claim 1, wherein the exposed portion is formed in an end part of the rear surface side of the connection surface by which the flexible printed circuit board is connected to the display panel.
