Problems solved by technology

However, the existence of the cover layer not only increases the overall thickness of the display device, but also makes the device produce color shift at a certain angle.
[0005] In addition, the position of the general spacer is set in red, Next to one of the blue or blue color layers, however, in order to set the spacer, the width of the black matrix area of ​​the color must be increased, so the size of the display area of ​​the color is reduced accordingly, and the aperture ratio of the color is sacrificed

Abstract

The invention discloses an organic electroluminescent displaying device and a manufacturing method of the organic electroluminescent displaying device. The organic electroluminescent displaying device at least comprises a first component and a second component, wherein the first component comprises a first substrate and an organic electroluminescent unit formed on the first substrate, the second component forms a group together with the first component, and comprises a second substrate, and a filtering layer formed on the second substrate and a shading pattern layer formed on the second substrate. The filtering layer comprises a plurality of filtering zones, and the shading pattern layer is arranged on the colorful filtering zones and respectively surrounds on the periphery of the colorful filtering zones. The displaying device further comprises a plurality of spacers, the spacers are contacted with the filtering layer and correspond to the shading pattern layer, and the spacers are arranged between the first component and the second component.

Description

technical field [0001] The present invention relates to a display device and its manufacturing method, and in particular to an organic electroluminescence display device and its manufacturing method. Background technique [0002] Flat panel display devices such as liquid crystal display devices (Liquid Crystal Display Device, LCD), plasma display devices (Plasma Display Panel, PDP) or organic electroluminescent display devices (Organic Electroluminescent Display, OLED) are thinner and smaller than previous cathode ray tube display devices, so they have gradually become the current Common flat panel display devices. Among them, the organic electroluminescent display device has the advantages of thinness, flexibility, portability, full color, high brightness, power saving, wide viewing angle and high response speed. [0003] At present, monochrome OLED display technology has matured, but considering the level of the next-generation flat-panel display and its application, the ...
