Abstract:
1. A liquid crystal display panel, comprising: a color filter array substrate provided with a main column spacer and a sub column spacer; and a thin film transistor array substrate disposed in opposition to the color filter array substrate, wherein the thin film transistor array substrate comprises: a top film in contact with the main column spacer and a depressed portion disposed under the sub column spacer; a gate line and a data line crossing each other with a gate insulating film disposed therebetween; a thin film transistor provided at each crossing of the gate line and the data line; and a protective film having a contact hole for exposing a drain electrode of the thin film transistor; wherein the depressed portion includes at least one of the protective film and the gate insulating film and at least one of the protective film and gate insulating film has a thinner thickness at an area overlapped with the sub column spacer than an area overlapped with the main column spacer.
