Abstract

The embodiment of the invention provides a display device. The display device comprises a substrate, a planarized layer covering the substrate and a protective layer covering one side, deviating fromthe substrate, of the planarized layer; and the protective layer has thermal conductivity, transparency and insulativity. According to the embodiment of the invention, the protective layer with the thermal conductivity, transparency and insulativity covers the planarized layer, the planarized layer can be effectively protected, the planarized layer is prevented from deforming in a follow-up preparation process, loss of blue light in white light of the planarized layer is reduced, color temperature is increased, the white light is improved, and light emitting quality of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a method for preparing the display device. Background technique [0002] In the current research field of liquid crystal display panels, the material of the planarization layer used in the display panel is usually a resin material, which is prone to shrinkage under a long-term thermal process or sputtering process, resulting in blue light transmission of the planarization layer. The reduction of the pass rate leads to low intensity of blue light in the white light plus color film panel, low color temperature of white light, and yellowish color point, but the prior art has not yet proposed a solution to this problem. Contents of the invention [0003] The invention provides a display device to solve the problems of low blue-off intensity, low white light color temperature and yellowish color point of the existing display device. [0004] One aspect...
