In the present embodiment, for the liquid crystal display panel 100, the pixel sub-region 130 corresponding to the branch electrode 132 is a light-transmitting region, and the region corresponding to the main electrode 131 is a non-light-transmitting region; in the present application, the pixel sub-area 130 and the first color block 31 are correspondingly disposed, and incident light can simultaneously penetrate through the pixel sub-area 130 and the first color block 31 and be led out from the light-emitting side of the display panel 100; secondly, the main electrode 131 corresponds to the second color block 32, and since the area corresponding to the main electrode 131 is a non-light-transmitting area, the orthographic projection of the main electrode 131 on the second color block 32 is located in the second color block 32, that is, the area of the main electrode 131 needs to be smaller than the area of the second color block 32, that is, in the top view direction of the display panel 100, the second color block 32 covers the main electrode 131, extends toward the pixel sub-area 130, and overlaps with the branch electrode 132 in the pixel sub-area 130, so as to adjust the color gamut and the reflectivity of the display panel 100 by adjusting the thickness of the second color block 32.
In this embodiment, the area of the forward projection of the first color block 31 on the pixel sub-area 130 is smaller than the area corresponding to the pixel sub-area 130. The second color block 32 overlaps the branch electrode 132 in the pixel sub-area 130, that is, the area of the first color block 31 is smaller than the area of the pixel sub-area 130, and the color gamut and the reflectivity of the display panel 100 are adjusted by dual regulation of the size and the thickness of the area of the second color block 32.

In the current display panel 100, at a portion of the pixel electrode 13 close to the thin film transistor 120, due to the influence of the voltage of the metal layer in the thin film transistor 120, such as the gate, the source, or the drain, the voltage of the pixel electrode 13 in the area is inaccurate, and thus the liquid crystal alignment is abnormal, which causes a technical problem of abnormal display.
In this embodiment, please refer to fig. 7, based on fig. 5, in the present application, the third color-blocking block 33 is disposed between the pixel electrode 13 and the thin film transistor 120, and the region where the abnormal alignment is likely to occur is covered by the third color-blocking block 33 with a relatively small thickness, so that the color light passing through the third color-blocking block 33 is reduced, the white light passing through the third color-blocking block 33 is increased, that is, the amount of the abnormal color light in the region is reduced, thereby improving the abnormal display of the display panel 100, and simultaneously increasing the amount of the white light passing through the color-blocking, and increasing the reflectivity of the display panel 100.

In the present display panel 100, a coupling capacitance is formed between the Data line Data and the pixel electrode 13, so that a display abnormality may occur on a side of the pixel electrode 13 close to the Data line Data due to an alignment abnormality.
In the present application, the fourth color block 34 is disposed between the Data line Data and the first color block 31, so that the light passing through the abnormal region enters the fourth color block 34, the color light passing through the fourth color block 34 is reduced, the white light passing through the fourth color block 34 is increased, that is, the amount of the abnormal color light in the region is reduced, the technical problem of abnormal display of the display panel 100 is improved, meanwhile, the amount of the white light passing through the color block is increased, the reflectivity of the display panel 100 is improved, and the influence of the abnormal light in the region on the display effect is improved.
In the display panel 100 of the present application, the thickness of the second color block 32 in the blue color resistance unit is greater than the thickness of the second color block 32 in the red color resistance unit, and the thickness of the second color block 32 in the red color resistance unit is greater than the thickness of the second color block 32 in the green color resistance unit.
In this embodiment, since the light intensities of the different color lights are different, for example, the light intensity of the green light is the largest, the light intensity of the blue light is the smallest, and the red light is centered, in order to ensure that the light intensities of the different color sub-pixels are the same, it is possible to adjust the light intensities of the different color sub-pixels by adjusting the thicknesses of the different color second color blocking blocks 32.
In the present embodiment, since the intensity of the green light is maximized, the thickness of the second color resist 32 in the green color resist unit can be reduced appropriately; since the intensity of blue light is minimized, the thickness of the second color resist 32 in the blue color resist unit can be increased appropriately; since the intensity of red light is centered in blue and green light, the thickness of the second color block 32 in the red color block unit may not be adjusted.
This application is through the thickness that hinders the second colour of the unit 300 and hinder the piece 32 to the colour of different colours for the light intensity that sees through the light of three kinds of colours of red, green and blue is the same, guarantees that the colour gamut of the light-emitting light of each pixel unit is the same in display panel 100, has improved display panel 100's demonstration homogeneity.
On the basis of the present embodiment, since the light intensities of the light beams with different colors are different, in order to further improve the display uniformity of the display panel 100, the light intensities of the sub-pixels with different colors can be adjusted by adjusting the thicknesses of the first color blocking blocks 31 with different colors. For example, the thickness of the first color block 31 in the blue color resistance unit is greater than the thickness of the first color block 31 in the red color resistance unit, and the thickness of the first color block 31 in the red color resistance unit is greater than the thickness of the first color block 31 in the green color resistance unit, that is, the thickness of the first color blocks 31 of different colors may have the same relationship with the thickness of the second color blocks 32 of different colors.
