<p>PROBLEM TO BE SOLVED: To manufacture a liquid crystal display device having a high opening rate and good orientation of liquid crystals at a good yield by decreased production stages. SOLUTION: This liquid crystal display device is provided with gate signal lines 2, source signal lines 12 and interlayer insulating films of a two-layered structure so as to cover TFTs. The first layer 18a on the substrate side of these interlayer insulating films consist of a benzocyclobutene layer and the second layer 18b consists of a silicon oxide layer obtd. by subjecting the surface of the first layer 18a to an oxygen plasma treatment. The interlayer insulating films are provided thereon with pixel electrodes 11 which are connected to switching elements via contact holes penetrating the interlayer insulating films.</p> |
