1. A liquid crystal display panel, comprising:
a first display area;
a second display area;
sub-pixels arranged in an array, wherein the sub-pixels comprise first sub-pixels and second sub-pixels; and
wherein the first sub-pixels are disposed in the first display area, the second sub-pixels are disposed in the second display area, and a thickness of photoresist of at least a part of the second sub-pixels is smaller than a thickness of the photoresist of the first sub-pixels;
each of the second sub-pixels comprises at least one photoresist area and at least one light-transmitting area in a second direction, and a thickness of the photoresist in the at least one light-transmitting area is 0; each of the at least one photoresist area and a corresponding one of the at least one light-transmitting area are adjoining to each other and alternatively arranged along the second direction;
wherein each of the at least one photoresist area has an area greater than the corresponding one of the at least one light-transmitting area; or
for each of the at least one light-transmitting area, areas of two of the at least one photoresist area which are adjacent to the light-transmitting area are each smaller than an area of the light-transmitting area, and a sum of the areas of the two photoresist areas is greater than the area of the light-transmitting area; and
wherein a black matrix is arranged between the photoresist of every adjacent two of the second sub-pixels, and another black matrix is arranged between the photoresist of every adjacent two of the first sub-pixels, the black matrix has a smaller area than the another black matrix, and no black matrix is arranged between the photoresist of ones of the second sub-pixels and the photoresist of ones, which are adjacent to the ones of the second sub-pixels, of the first sub-pixels.
