Definitions
- Liquid crystal panel display device, and manufacturing method of liquid crystal panel
- Figs. 1 and 2 show the direction of light propagation.
- the black matrix 80 is usually further broadened in design to reduce the light leakage caused by the alignment deviation, but this method is at the expense of the aperture ratio, and at the same time, the light is reduced to another extent. Transmittance rate. Summary of the invention
- the orientation of the liquid crystal molecules corresponding to the thin film transistor region is different from the orientation of the liquid crystal molecules corresponding to the pixel display region.
- FIG. 3 is a schematic structural view of a liquid crystal panel in a state where no voltage is applied according to the first embodiment of the present invention
- FIG. 6 is a schematic structural view of a liquid crystal panel in a voltage-increasing state according to a second embodiment of the present invention
- FIG. 7 is a schematic structural view of a liquid crystal panel in a state where no voltage is applied according to a third embodiment of the present invention
- a liquid crystal panel includes an array substrate 10, an opposite substrate 20 disposed opposite to the array substrate 10 and disposed opposite the array substrate 20, and a liquid crystal layer 30 disposed between the array substrate 10 and the opposite substrate 20.
- the array substrate 10 and the opposite substrate 20 are disposed in parallel, and the liquid crystal layer 30 is filled in the space between the array substrate 10 and the opposite substrate 20.
- the array substrate 10 includes a plurality of gate lines (not shown), a plurality of data lines 70, a plurality of gate lines and a plurality of data lines 70 defining a plurality of pixel units, and the pixel unit includes a pixel display area 1 and a thin film transistor. Area (not shown).
- the pretilt angle of the first alignment layer 3 of the thin film transistor region is the same as the pretilt angle of the second alignment portion 32.
- the first alignment layer described in the embodiment of the present invention includes the first alignment portion and the second alignment portion, that is, the first alignment portion and the second alignment portion are a part of the first alignment layer.
- the second alignment layer described in the embodiment of the present invention includes the third alignment portion and the fourth alignment portion, that is, the third alignment portion and the fourth alignment portion are part of the second alignment layer.
- the pretilt angle of the alignment layer (orientation portion) is the angle of the slope of the surface groove of the alignment layer (orientation portion), and determines the pretilt angle of the liquid crystal molecules.
- the orientation direction of the alignment layer (orientation portion) refers to the direction in which the alignment layer is rubbed during the rubbing alignment treatment.
- Step 3 Align the array substrate 10 with the opposite substrate 20.
- the material of the first protective layer 13 and the material of the second protective layer 23 are both quartz.
