Display panel and manufacturing method thereof

Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a film transistor array base plate, a color optical filter base plate and a liquid crystal layer, wherein the color optical filter base plate and the film transistor array base plate are overlapped and combined into a whole, the film transistor array base plate comprises a first surface and a second surface, a first orientation layer is arranged on the second surface, and comprises a first orientation material, the color optical filter base plate comprises a third surface and a fourth surface, a second orientation layer is arranged on the third surface, and comprises a second orientation material, the liquid crystal layer is arranged between the second surface and the third surface, liquid crystal molecules in the liquid crystal layer are negative liquid crystal molecules, the first orientation layer and the second orientation layer are respectively formed by imprinting through the first orientation material and the second orientation material and formed by ultraviolet irradiation. The display panel and the manufacturing method of the display panel has the advantages that local area of the orientation layers can be prevented from generating poor orientation phenomena, the light leakage is reduced, the contrast ratio is improved, and the anchoring capability of the orientation layers can be favorably improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. 【Background technique】 [0002] There are generally two alignment methods of traditional liquid crystal display panels: [0003] The first type: rubbing (Rubbing). [0004] Due to the mature conditions of materials, processes, equipment, etc., rubbing is generally used to align the alignment layer at present. [0005] In addition to the chemical force between polymer chains and liquid crystal molecules in the alignment layer after rubbing treatment, the physical and mechanical interaction between rubbed grooves and liquid crystal molecules greatly increases the anchoring energy of the alignment layer. [0006] However, in the process of rubbing, on the one hand, the irregular local area of ​​the rubbing cloth on the rotating roller will easily lead to poor alignment in the local area of ​​the alignment layer, which will aff...

Problems solved by technology

[0010] However, in the photo-alignment technology, the anchoring energy of the alignment layer to the liquid crystal molecules is only composed of the chemical force between the polymer chains on the surface of the alignment layer and the liquid crystal molecules, which will lead to insufficient anchoring energy of the alignment layer, so its The reliability is relatively poor, and the reliability is characterized by ISP (Image Sticking Parameter, image matching parameter)

[0011] In summary, the above two alignment methods are difficult to effectively improve the display quality of LCD panels
