Problems solved by technology

However, although the inclusion of an inorganic layer in the protective layer can improve the adhesion between the protective layer and the glass substrate, it may cause the light transmittance of the glass substrate to deteriorate, and an additional process is required due to the inclusion of the inorganic layer. It may also increase its defect rate

Abstract

The invention provides an optical wafer, which comprises a basis material and at least one protection layer. The protection layer is positioned on at least one surface of the basis material and has an organic layer, and the organic layer comprises a thermosetting resin used for increasing the basis material toughness. The protection layer and the basis material have good adherence with each other. The optical wafer protected by the protection layer can not produce warp and has high optical transparency.

Description

Technical field [0001] The present invention relates to an optical sheet, in particular to an optical sheet with a reinforced structure. Background technique [0002] At present, electronic products have been developing towards lightness and thinness. Because cathode ray tubes (CRT) cannot achieve lightness and thinness and low power consumption, liquid crystal displays (LCD), plasma display panels (PDP), and electroluminescence Display (electroluminescent display; ELD), vacuum fluorescent display (vacuum fluorescent display) and other flat-panel displays are replaced. Among them, the liquid crystal display has become the mainstream of the market due to its advantages of high image quality, low radiation, low power consumption, and better space utilization. [0003] The method used to make the liquid crystal display lighter and thinner is nothing more than thinning the glass substrate that accounts for a certain weight in the liquid crystal display, or replacing the glass substrat...
