Organic electroluminescent display device, organic electroluminescent display device manufacturing method and display equipment

Abstract

The invention discloses an organic electroluminescent display device, an organic electroluminescent display device manufacturing method and display equipment. According to the organic electroluminescent display device, before final packaging treatment is carried out on an organic electroluminescent pixel array, a phase difference film and a polarization function film in a circular polarizer are sequentially attached to the organic electroluminescent pixel array, and then packaging treatment is carried out on the organic electroluminescent pixel array with the phase difference film and the polarization function film attached, wherein TAC films needing to be attached to the two sides of a polarization function film in an existing circular polarizer or other unnecessary films like a binder layer are eliminated. In this way, the transmittance and contrast ratio of the display device can be improved; in addition, the overall thickness of the display device can be decreased to make the display device lighter and thinner and avoid the problem of curling difficulty. Furthermore, because the phase difference film and the polarization function film are attached under vacuum protection or inert gas protection or nitrogen protection without interference of water vapor, the durability of the circular polarizer is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent display device, a manufacturing method and a display device. Background technique [0002] At present, compared with traditional liquid crystal display devices (Liquid Crystal Display, LCD), organic electroluminescent display devices (Organic Electroluminescent Display, OLED) have the characteristics of fast response, wide color gamut, ultra-thin, and flexibility. Has gradually become the mainstream of the display field. [0003] The structure of the OLED display device mainly includes: a base substrate, an organic electroluminescent pixel array fabricated on the substrate substrate; wherein, each organic electroluminescent pixel array includes an anode and a cathode arranged oppositely, and between the luminous layers. The light emission of the OLED display device is realized by exciting the organic material in the light-emitting layer to emit li...
