Display substrate, display device and manufacturing method thereof

Abstract

A display substrate, display device and its production method. The display device includes: an orderly porous film, which includes sub -pixels arranged in matrix. There are multiple holes in each sub -pixel area.The surface of the orderly porous film is an unrealistic angle, and each hole has an opening on the surface of the ordered porous film; multiple quantum dots are set in at least part of the pores; and separate settings in separate settings, respectively.The first electrode layer and the second electrode layer on both sides of the order of multiple porous films include the sub -electrode set by multiple intervals, which correspond to the sub -pixel area of the sub -electrode, respectively.The display substrate, and the display device and its production method have high color gamut and quantum dot lighting efficiency.

Description

technical field

[0001] Embodiments of the present disclosure relate to a display substrate, a display device and a manufacturing method thereof. Background technique

[0002] A liquid crystal display usually utilizes a color filter layer included in it to filter, for example, white light emitted by a backlight module to form light of different colors through light mixing, thereby realizing color display. Because the material of the color filter layer itself includes small dye molecules, which will absorb part of the light emitted by the backlight module, the luminous efficiency of the color filter layer is limited; in addition, the backlight module usually uses LED (light-emitting diode) as the light source, and the LED emits The half peak width of the light is wide and the color of the light formed by the interaction with the material of the color filter layer is impure.

[0003] As a new type of semiconductor nanomaterial, quantum dots have many unique nano-properties. I...
