Title: DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF
Abstract:
A Display device and manufacturing method thereof, used to solve the problem in the prior art of low transmission rate of the light of an OLED display device used for display. Provided in an embodiment of the present invention is a display device, comprising a first substrate (1) and an opposite second substrate (13), the first substrate (1) having at least one metal pattern thereon, and the area of an overlapping region of the metal pattern and pixel display region being smaller than the area of the pixel display region; the present invention is characterized by further comprising: a polarizer (16) located on the outer side of the second substrate (13) facing away from the first substrate (1); a polyvinyl alcohol (PVA) layer (16A) included by the polarizer (16) completely covers the at least one metal pattern, and the area of the overlapping region of the PVA layer (16A) and the pixel display region is smaller than the area of the pixel display region. The present invention improves the transmission rate of the light of an OLED display device used for display.
