Problems solved by technology

[0008] However, in the conventional image display device described in Patent Document 1, since the spacer provided to maintain a gap between the front surface of the image display panel and the transparent protective plate is made of glass fibers, glass beads or resin beads, etc. Since it is made of a hard material with a large Young's modulus, there is a problem that an impact is applied to the front surface of the image display device from the outside when performing pressure defoaming in the autoclaving process during the manufacture of the image display device or when the image display device is used. cracks on the front surface of the spacer, transparent protective plate, or image display panel, resulting in display defects such as display spots

Abstract

This image display device (100) is provided with a liquid crystal panel (10) having an image display area; a transparent protection plate (20) disposed on the image display area; a spacer part (32) made of synthetic rubber and disposed between the image display area and the transparent protection plate (20); and a charging unit (31) disposed between the image display area and the transparent protection plate (20) and made of synthetic resin having a Young's modulus smaller than the spacer part (32). According to the present invention, while ensuring a gap between the image display panel (10) and the transparent protection plate (20), breakage can be unlikely to occur even when force is applied from the front surface of the image display device (100).

Description

technical field [0001] The present invention relates to an image display device including a transparent protective plate on the front side of an image display panel. Background technique [0002] The image display device has an image display panel such as a liquid crystal panel or an organic EL (Electro-Luminescence: electroluminescent) panel that displays an image. A transparent protective plate such as glass or transparent resin is provided on the front surface side of the image display panel. In such an image display device, by providing a transparent adhesive layer between the front surface of the image display panel and the transparent protective plate, a predetermined interval is ensured between the front surface of the image display panel and the transparent protective plate, and the adhesive is applied from the outside. The impact is not applied directly to the front surface of the image display panel and is mitigated. [0003] In the existing image display device,...
