ABSTRACT:
A liquid crystal display device which includes first and second organic interlaminar insulating films between pixel electrode and wire. The first interlaminar insulating film directly covers source electrode, source wire, drain electrode and back channel. Underlying one of the organic interlaminar insulating films directly contacts a channel part of a TFT. This provides an active matrix type liquid crystal display device with high transmittance and capable of bright displaying, which includes an active matrix wiring substrate having a structure of overlapping wires with a pixel electrode. The device can be prepared at low cost only through 5 photolithographic steps, i.e., without increasing the photolithographic steps as compared with those of the prior liquid crystal display device having high aperture ratio.
