Abstract:
1. A method for manufacturing a display apparatus comprising a liquid crystal layer sandwiched between a first substrate having a first electrode and a second substrate having a second electrode, comprising steps of: forming a thin film transistor on said first substrate, covering said thin film transistor to form at least a single-layer insulating film, covering said insulating film to form a reflective material layer which is then patterned such that the formed reflective material layer remains on a predetermined pixel region other than a region corresponding to the active layer of said thin film transistor to form a reflective layer, covering said reflective layer to form a passivation film, forming a contact hole which penetrates said passivation film and said insulating film on the region in which said reflective layer is removed, the region corresponding to the active layer of said thin film transistor; exposing said active layer with use of said passivation film as a protective film for said reflective layer during slight etching to expose said active layer at a bottom of said contact hole when forming said contact hole, and covering said passivation film and said active layer exposed with transparent conductive material to form said first electrode which is then connected to said active layer through said contact hole, wherein said reflective layer is insulated from both said active layer and said first electrode.
