Problems solved by technology

[0003] In the OLED display device in the prior art, the light emitted by the OLED is largely confined inside the product, which significantly reduces the ability of the OLED display device to emit light from the front.
Usually, in order to improve the front light output ability of OLED display devices, a large number of functional structures and functional layers are set in OLED display devices to improve the front light output ability of products, which leads to the continuous increase of the thickness and weight of OLED display devices, and reduces the OLED display device.

Abstract

The invention provides a display substrate and a display device, and belongs to the technical field of display. The invention provides a display substrate. The display substrate comprises a substrate body, a plurality of light-emitting units arranged on the substrate body and a color filter layer arranged on the sides, away from the substrate body, of the light-emitting units. The color filter layer comprises a plurality of color filters and first auxiliary function parts arranged between the adjacent color filters, and the first auxiliary function parts are used for reflecting light emitted by the light emitting units to the display side of the display substrate. One color filter is arranged corresponding to one light emitting unit. The refractive index of the first auxiliary function part is smaller than that of the color filter in contact with the first auxiliary function part.

Description

technical field [0001] The present disclosure belongs to the field of display technology, and in particular relates to a display substrate and a display device. Background technique [0002] With the development and progress of display technology, for existing display devices, organic light emitting diode (Organic Light Emitting Diode, OLED) is a current-mode light-emitting device, because it is different from TFT-LCD (hin Film Transistor Liquid Crystal Display (thin film transistor liquid crystal display device) has the advantages of self-illumination, fast response, wide viewing angle, high brightness, bright color, thin and light volume, etc., and is more and more used in the field of high-performance display. [0003] In the OLED display device in the prior art, the light emitted by the OLED is largely confined inside the product, which significantly reduces the ability of the OLED display device to emit light from the front. Usually, in order to improve the front light...
