Abstract

The invention is applicable to the field of display technology and provides an OLED substrate, a production method of the OLED substrate and a flexible display device. The OLED substrate comprises a substrate body, multiple first electrodes and a pixel definition layer, wherein the pixel definition layer is provided with multiple through holes which respectively and correspondingly expose part ofthe multiple first electrodes; the substrate body comprises multiple pixel regions, wherein each pixel region comprises a first sub-pixel region, a second sub-pixel region and a third sub-pixel region, and the multiple through holes are located in the multiple sub-pixel regions respectively; and the pixel definition layer comprises first color-filtering layers, second color-filtering layers and third color-filtering layers corresponding to the first sub-pixel regions, the second sub-pixel regions and the third sub-pixel regions respectively, and the first color-filtering layers, the second color-filtering layers and the third color-filtering layers are made of a color-filtering material in a first color, a color-filtering material in a second color and a color-filtering material in a thirdcolor respectively. Through the OLED substrate, the technical problems of color cast, low light-emitting efficiency and high production cost of an existing OLED device can be solved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an OLED substrate, a method for manufacturing the OLED substrate, and a flexible display device. Background technique [0002] There is a micro-resonator effect in top-emitting OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) devices. The micro-resonator effect means that the photon density of different energy states is redistributed, so that only the light of a specific wavelength conforms to the resonance mode, and can It is emitted at a specific angle, so the half-width of the light wave will be narrowed, and the light intensity and wavelength of the light wave at different angles will also be different. This will cause the luminous intensity and color to change with the angle in the application of the display device. its display effect. The existing method to solve the color shift of top-emitting OLED devices is to paste a layer of color filters...
