Abstract

A method for producing a liquid crystal display device includes: a pair of insulating substrates; a liquid crystal layer interposed between the pair of insulating substrates; switching elements arranged in a matrix on one of the pair of the insulating substrates; gate lines and data lines, arranged to intersect each other, for controlling the switching elements; and pixel electrodes provided above the gate lines and the data lines with an organic insulating film therebetween. The method includes the steps of forming a transparent conductive film on the organic insulating film at a first temperature; annealing the transparent conductive film at a second temperature equal to or lower than the first temperature; and patterning the transparent conductive film to form the pixel electrodes after the step of annealing.
