Abstract

The present invention relates to a display device, a method for manufacturing the display device, and a display unit. The display device includes: a TFT array substrate; a light-emitting layer disposed on the TFT array substrate and including a plurality of pixel units; and a scattering layer disposed between the TFT array substrate and the light-emitting layer and including a light-blocking separating wall and a plurality of scattering units separated by the light-blocking separating wall, wherein the scattering units and the pixel units correspond to each other one to one. The display device, by means of the scattering layer arranged between the substrate and the light-emitting layer and having scattering units corresponding to the pixel units of the light-emitting layer one to one, canprevent a light loss in a waveguide mode and improve light-emitting efficiency. In addition, the light-blocking separating wall can prevent crosstalk caused by the scattered light between adjacent pixel units and avoid a fuzzy phenomenon. The scattering layer can also improve an image quality loss caused by the uneven arrangement of factor pixels, and achieves the display effect of a high-resolution display, thereby satisfying a requirement for high resolution.

Description

technical field [0001] The present invention relates to the technical field of displays, in particular to a display device and a display device for preparing the display device. Background technique [0002] With the increasing demand for high-resolution displays, some technologies aimed at achieving high-resolution have emerged. Especially when the equipment and production process for color pixel generation have certain scale limitations, in order to achieve the smaller pixel size required for high resolution, it is often necessary to explore how to break through the resolution limitations of the equipment and process. For example, in the printing display technology, the ink droplet size of the current common inkjet printing equipment cannot be infinitely reduced. Correspondingly, the printing pixels can only be accurately printed above a certain size. However, the current equipment technology limit is often difficult to meet the requirements for higher resolutions in the...
