Abstract
A transmissive liquid crystal display apparatus includes a liquid crystal layer interposed between a first substrate and a second substrate. The first substrate includes gate lines, source lines and switching devices provided in a vicinity of intersectional portions of the gate lines and the source lines. The switching devices include gate electrodes connected to the gate lines, source electrodes connected to the source lines and drain electrodes connected to pixel electrodes for applying a voltage to the liquid crystal layer. An interlayer insulating film having high transparency is provided above the switching devices, the gate lines and the source lines. The interlayer insulating film has roughness on its surface. A height difference of the roughness is 50 nm or less. The pixel electrode formed of a transparent conductive material is provided on the interlayer insulating film.
