摘要:
Disclosed is a method for manufacturing a thin film transistor LCD device, in which a counter and a gate bus line are made in a single photolithography process, and a channel of a thin film transistor, a source electrode, a drain electrode, ohmic contacts for the source and drain electrodes are made in a single photolithography process. The method involves the steps of forming a first photoresist layer on said deposited metal layer for the gate bus line; exposing said first photoresist layer to a scanning light, so that the portion of the first photoresist layer disposed over a counter electrode region for forming said counter electrode may be partially lightened; patterning said first photoresist layer so that an area of the metal layer for the gate bus line lying under the partially lightened portion of the first photoresist layer may not be exposed; patterning said metal layer for the gate bus line by using said patterned first photoresist layer as a barrier layer so that said counter electrode region and a gate bus line region may be defined; patterning said transparent conductive layer for the counter electrode by using said patterned metal layer as a barrier layer so that said counter electrode may be formed; patterning said metal layer for the gate bus line by using said patterned first photoresist layer as a barrier layer so that said gate bus line may be formed.

An embodiment of the present invention relates to a liquid crystal display. An upper surface alignment layer in the liquid crystal display is arranged to comprise, in the direction from a color filter substrate to a liquid crystal layer, a first upper surface alignment layer, a color washout compensation film layer and a second upper surface alignment layer; an alignment direction of the color washout compensation film layer is opposite to the pre-alignment direction of the liquid crystal layer. In the technical solution, the color washout compensation film layer is used to rectify the color washout problem occurring when the screen of a liquid crystal display screen of a fringe field switching mode is viewed from both the left side and right sides.
