Problems solved by technology

Since the half-tone mask process forms columnar spacers 30 of different heights under different light intensities, higher exposure intensity will affect the columnar spacers 30 with lower exposure intensity, resulting in lower support strength.
Moreover, the production cycle of the half-tone mask process is long and the cost is high, which is not conducive to reducing production costs

Abstract

A color filter substrate, comprising a transparent substrate and a color resist layer arranged on the transparent substrate, a black matrix and columnar spacers, the black matrix is ​​arranged on the first surface of the transparent substrate, the The color-resisting layer is arranged on the first surface of the transparent substrate and covers the black matrix; the color-resisting layer has a body part and a bump extending from the body part to a direction away from the transparent substrate ; The columnar spacer includes a main spacer and an auxiliary spacer, the main spacer is arranged above the position of the protrusion, and the auxiliary spacer is arranged above the body part. The color filter substrate of the present invention does not need to use a half-tone mask process when manufacturing the columnar spacers, effectively reducing production costs, and the support strength of the produced columnar spacers is uniform. The invention also relates to a liquid crystal display device.
