1. A liquid crystal display panel, comprising at least a first region and a second region, wherein the liquid crystal display panel comprises:
an array substrate comprising a first substrate, a first alignment layer disposed on a side of the first substrate, and a pixel electrode layer comprising a plurality of pixel electrodes;
a color filter substrate comprising a second substrate and a second alignment layer disposed on a side of the second substrate facing the array substrate, wherein the second alignment layer is disposed opposite to the first alignment layer; and
liquid crystal molecules disposed between the array substrate and the color filter substrate;
wherein in a film thickness direction, a sum of a thickness of the first alignment layer and a thickness of the second alignment layer in the first region is greater than a sum of a thickness of the first alignment layer and a thickness of the second alignment layer in the second region;
a plurality of first protrusions are disposed on the pixel electrode layer at intervals, any one of the pixel electrodes is disposed opposite to at least one of the first protrusions, and different pixel electrodes have different first protrusions with different heights that correspond to a transmittance of a pixel region; and
each of the pixel electrodes comprises a body portion, a slit portion disposed in the body portion, and a slit end disposed at a peripheral edge of the body portion and a peripheral edge of the slit portion; and a sum of a thickness of the first alignment layer and a thickness of the second alignment layer at the slit end, a sum of a thickness of the first alignment layer and a thickness of the second alignment layer at the body portion, and a sum of a thickness of the first alignment layer and a thickness of the second alignment layer at the slit portion decrease sequentially.
