Patent ID: 8633044

Claim:
A method for fabricating a display device by bonding an active matrix substrate to a counter substrate via a frame-like sealing member, the method comprising: forming a first conductive film having a predetermined pattern on a substrate by using a first mask; forming a first insulating film covering the first conductive film on the substrate; forming a semiconductor layer having a predetermined pattern on the first insulating film by using a second mask; forming a second conductive film having a predetermined pattern on the first insulating film by using a third mask; forming an interlayer insulating film made of a photosensitive organic insulating film having a predetermined pattern by using a fourth mask to cover part of the first insulating film on which the semiconductor layer and the second conductive film have been formed; etching part of the first insulating film by using the interlayer insulating film as a mask; forming a transparent electrode having a predetermined pattern on the interlayer insulating film by using a fifth mask, wherein in the forming the first conductive film, part of the first conductive film is formed in a region in which the sealing member is to be formed, in the forming the semiconductor layer, part of the semiconductor layer is formed in the region in which the sealing member is to be formed, in the forming the interlayer insulating film, the interlayer insulating film on the semiconductor layer is removed in the region in which the sealing member is to be formed, in the etching part of the first insulating film, the first insulating film in the region in which the sealing member is to be formed is etched by using the semiconductor layer as a mask, in the forming the transparent electrode, the semiconductor layer in the region in which the sealing member is to be formed is removed by etching simultaneously with the forming the transparent electrode; and providing the sealing member on the first insulating film from which the semiconductor layer has been removed.
