Problems solved by technology

[0003] A display panel using quantum dot materials includes a color filter substrate and a backlight substrate oppositely arranged, and a supporting structure needs to be set between the two to ensure the thickness consistency of the display panel. However, the current color filter substrate is close to the side of the backlight substrate. Poor surface flatness leads to poor support between the color filter substrate and the backlight substrate, which leads to poor display of the display panel due to poor thickness consistency

Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and can improve display defects caused by poor thickness uniformity of the display panel. The display panel includes: a plurality of sub-pixel areas; a backlight and a color filter layer located on the light emitting side of the backlight, the color filter layer includes a first color quantum dot color filter located in the first color sub pixel area, and a second color sub pixel area located in the color filter layer. The quantum dot color film of the second color and the third optical film layer located in the sub-pixel area of ​​the third color; the light emitted by the backlight source is the same color as the third color; at least one sub-pixel area of ​​the first color and at least one adjacent to it A spacer is provided at the junction of a sub-pixel area of ​​the second color, the spacer is located between the backlight source and the color filter layer, and the spacer and the third optical film layer are prepared in the same layer.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] Quantum dots (Quantum Dots) materials have the advantages of concentrated luminescence spectrum, high color purity, and continuously adjustable luminescence spectrum. Using these advantages to apply quantum dot materials to display panels can effectively improve the color gamut and color reproduction capabilities of display panels. . [0003] A display panel using quantum dot materials includes a color filter substrate and a backlight substrate oppositely arranged, and a supporting structure needs to be set between the two to ensure the thickness consistency of the display panel. However, the current color filter substrate is close to the side of the backlight substrate. Poor surface flatness leads to poor support effect between the color filter substrate and the backlight substrate, which leads to ...
