Embodiment 1

[0028] figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. Such as figure 1 As shown, the liquid crystal display device includes a substrate main body 10 and an alignment film 20 formed on the substrate main body 10. The alignment film 20 is composed of a first alignment film region 21 and a second alignment film region 22 arranged in sequence. The first alignment film region 21 and the second alignment film region 22 have different orientation characteristics, specifically: the first alignment film region 21 and the second alignment film region 22 are coated with different orientation materials, so that the first alignment film region 21 and the second alignment film region There is a set pencil hardness difference between the alignment film regions 22, and after subsequent rubbing treatment, there is a set orientation angle difference (hook angle difference) between the first alignment film region 21 and the second alignment film region 2...

Embodiment 2

[0033] figure 2 It is a structural schematic diagram of Embodiment 2 of the present invention. Such as figure 2 As shown, the alignment film region may be a block alignment film region with one or several pixels as the unit, specifically: the third alignment film region 23, the fourth alignment film region 24, and the fifth alignment film region 25, each phase The adjacent alignment film regions are coated with different orientation materials, and each adjacent alignment film region has different orientation characteristics, specifically: there is a specific pencil hardness difference between the alignment film regions; There is a specific orientation angle difference between them. Among them, the alignment film regions with different orientation characteristics: the third alignment film region 23, the fourth alignment film region 24 and the fifth alignment film region 25 are respectively arranged above the colored resins of different colors, and the surface of the substra...

Embodiment 3

[0038] image 3 It is a structural schematic diagram of Embodiment 3 of the present invention. Such as image 3 As shown, the alignment film region is composed of a central alignment film region 26 and a peripheral alignment film region 27, and each alignment film region is coated with a different orientation material. Wherein, each alignment film area is coated with different orientation materials, and each alignment film area has different alignment characteristics, specifically: an alignment film with relatively good light transmission is formed in the middle alignment film area 26, and an alignment film with relatively good light transmission is formed in the peripheral area 26. The alignment film region 27 forms an alignment film with relatively poor light transmittance.

[0039] Due to the difference in the structure of the liquid crystal display device (for example, there is a sealant in the peripheral part and no sealant in the middle part), the central region and th...

Abstract

The invention relates to a baseplate used for an LCD apparatus, comprising a baseplate body and an alignment film formed on the baseplate body. The alignment film consists of at least two alignment film zones with different orientations and the adjacent alignment film zones are formed by spraying different orienting materials. The invention also relates to a manufacturing method for the LCD apparatus baseplate, including the following steps: step1, at least two kinds of orienting materials with different orienting characteristics are filled into at least two nozzles; step2, at least two nozzles are positioned at an appointed zone on the surface of the baseplate body; step3, at least two nozzles are adopted to spray the orienting materials toward the appointed zone to lead the surface of the baseplate body to be formed by spraying at least two kinds of different orienting materials with different orienting characteristics; step4, directional friction is carried out for at least two alignment film zones. The invention eliminates the condition of uneven response speed and enhances the contrast and effectively enhances the display quality of the LCD apparatus.

Description

technical field [0001] The invention relates to a liquid crystal display device and a manufacturing method thereof, in particular to a liquid crystal display device with multiple alignment film regions and a manufacturing method thereof. Background technique [0002] The liquid crystal display device is one of the most used flat panel display devices at present. It is mainly composed of two substrates and a liquid crystal layer injected between the two substrates. The two substrates are each equipped with electrodes that can generate an electric field. The electrodes generate a voltage The liquid crystal molecules in the rear liquid crystal layer move with the electric field, and the liquid crystal molecules rotate in a certain direction under the action of the electric field, so that light passes through the liquid crystal layer according to a certain refractive index. On the other hand, an alignment film (Alignment Film) is coated on the main body of the two substrates, an...
