1. A color filter substrate comprising a plurality of elementary pixels, wherein each of the elementary pixels comprises sub-pixels in four colors; among the sub-pixels in four colors, a sub-pixel in at least one of the colors has a number larger than or equal to 2; in each pixel row, the elementary pixel, which is composed of the first-color sub-pixel, one of the fourth-color sub-pixels, the second-color sub-pixel, one of the fourth-color sub-pixels, the third-color sub-pixel and one of the four-color sub-pixels, is periodically arranged; and except for a first pixel row, the arranging order of the sub-pixels of each elementary pixel of each pixel row is that, a right shift by one of the sub-pixels which has a larger area and one of the sub-pixels which has a smaller area is made on the basis of a previous row, and the arranging order of the sub-pixels of each elementary pixel of the first pixel row is that, a left shift by one of the sub-pixels which has a larger area and one of the sub-pixels which has a smaller area is made on the basis of a second pixel row; or except for a first pixel row, the arranging order of the sub-pixels of each elementary pixel of each pixel row is that, a left shift by one of the sub-pixels which has a larger area and one of the sub-pixels which has a smaller area is made on the basis of a previous row, and the arranging order of the sub-pixel of each elementary pixel of the first pixel row is that, a right shift by one of the sub-pixel which has a larger area and one of the sub-pixel which has a smaller area is made on the basis of a second pixel row.
