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

The invention discLoses a coLor fiLter pLate, which comprises a transparent substrate, a coLor barrier Layer, a bLack matrix and a coLumnar spacer on the transparent substrate which are arranged on the transparent substrate, and the bLack matrix is arranged on a first surface of the transparent substrate, the coLor barrier Layer is arranged on the first surface of the transparent substrate and covers the bLack matrix; the coLor barrier Layer is provided with a body part and a convex bLock extending from the direction of the body part away from the transparent substrate; The coLumnar spacer comprises a master spacer and a auxiLiary cushion arranged above the position of the convex bLock, and the auxiLiary cushion is arranged at the upper part of the body part. The coLor fiLter base pLate of the invention does not need to use haLf-tone mask process when making the coLumnar spacer, effectiveLy Lowering the production cost, and the supporting strength of the coLumnar spacer is one. The invention aLso reLates to a Liquid crystaL dispLay device.
