Abstract:
An array substrate comprising:a base substrate;a semiconductor layer formed on said base substrate;a first conductive layer disposed on said semiconductor layer;a first inter-layer insulating film made of an inorganic material over said semiconductor layer;a second inter-layer insulating layer made of an organic material on said first conductive layer and said first inter-layer insulating film; anda second conductive layer formed on said second inter-layer insulating film,said second inter-layer insulating film has a hole extending therethrough to a top surface of said first conductive layer,said hole having a tapered inner wall surface,said organic material of said second inter-layer insulating film fully covering said first inter-layer insulating film at the inner wall surface of said hole, andsaid second conductive layer being connected to said first conductive layer via said hole.
