Abstract

To provide an image display which is capable of preventing fracturing of a substrate which is attributable to a substrate expansion arising from heating or humidification during a manufacture process, impact in use, or distortion when curved display is conducted, a connection failure between a semiconductor chip and a wiring terminal which are mounted on the substrate, and crack occurring in the substrate in the vicinity of an area where the semiconductor chip is mounted, with no need to add members and with no limit of pulling the wiring around. An image display part is formed on one surface of a flexible substrate, and a groove with a depth not reaching a thickness of the substrate is continuously or intermittently defined in another surface of the substrate.

Claims (9)

1. An image display, comprising:

a display panel;

a first frame disposed on one surface of the display panel; and

a second frame disposed on another surface of the display panel, in which the display panel, the first frame, and the second frame are modularized,

wherein the display panel has a flexible substrate on one surface of which is formed an image display part, and in another surface of which is continuously or intermittently formed a groove having a depth not reaching a thickness of the substrate, and

wherein a projection is formed on each surface of the first frame and the second frame at the display panel side so as to face an area of the substrate in which no groove is formed, and hold the substrate.

2. The image display according to claim 1 , wherein the first frame and the second frame are so curved as to project in the same direction.

3. The image display according to claim 1 , wherein the display panel is a liquid crystal display panel, and a backlight is disposed between the display panel and the second frame.
