Abstract
A liquid crystal display device and a manufacturing method thereof which can suppress chipping of an alignment film or the like are provided. A liquid crystal display device and a manufacturing method thereof which can obviate the complication of manufacturing steps and the increase of a manufacturing cost are also provided. A liquid crystal display device includes: a TFT substrate; a counter substrate; and liquid crystal sandwiched between the TFT substrate and the counter substrate. A plurality of color filters are arranged on the counter substrate, and spacers are formed by stacking the plurality of color filters and by covering a surface of stacked color filters with an overcoat layer. Pedestals are formed on the TFT substrate in a state where the pedestal faces the spacer in an opposed manner. The pedestal is formed by stacking at least a semiconductor layer and a metal layer formed which are simultaneously with a thin film transistor on the TFT substrate. A width of a pedestal portion constituted of the semiconductor layer is substantially equal to a width of the spacer.
