Problems solved by technology

Among them, the red sub-pixel area and the green sub-pixel area are filled with quantum dot materials. The quantum dot material allows users to receive red or green light at various angles, while the blue sub-pixel area needs to pass through the blue light source. Usually filled with transparent materials or even not filled, this will cause the problem of viewing angle deviation in the blue sub-pixel area, and at the same time, the intensity of blue light emitted by the blue sub-pixel area is strong, which will cause certain damage to the user's eyes

[0040] see figure 2 , the protruding structure 123 and the transparent conductive film layer 125 are made of the same material. The transparent conductive film layer 125 is made of metal oxide, such as indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, or other suitable oxides, or is a stack layer of at least two of the above.

[0041] Optionally, the protruding structure 123 may be formed during the process of preparing the transparent conductive film layer 125 , that is, the patterned transparent conductive film layer 125 is obtained. Under the basic structure of the color filter layer 110, after completing the encapsulation, flattening layer 127 and polarizing layer 126 and other processes, a transparent photoresist structure of unequal height is prepared above the polarizing layer 126. This transparent photoresist structure of unequal height The resistive structure can be completed by photolithography process, and ...

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel with a quantum dot color filter layer and a display device with the display panel. Background technique [0002] The color of the liquid crystal display is realized by means of a color filter (CF, color filter). However, traditional color filters have the disadvantages of poor utilization of light and low transmittance, and the transmission peak of traditional color-resist materials is wide, the color density is limited, and it is difficult to achieve a wide color gamut, which can no longer satisfy users. Requirements for display quality. Quantum dots (Quantum Dots, QDs) are spherical semiconductor nanoparticles composed of II-VI or III-V elements, with a particle size generally ranging from a few nanometers to tens of nanometers. Due to the small half-width of quantum dot materials and the luminescent color can be easily adjusted by the size, str...
