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, especially an optical sheet with a reinforced structure. Background technique [0002] At present, electronic products have developed towards lightness and thinness. Since cathode ray tubes (CRT) cannot achieve lightness and thinness and low power consumption, liquid crystal displays (LCD), plasma display panels (PDP), and electroluminescence are gradually being used. 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 thinner and lighter is nothing more than thinning the glass substrate that accounts for a certain weight in the liquid crystal display, or replacing the g...
