Abstract:
1. A method for manufacturing a display device, the display device including: an insulating layer including a first region and a second region arranged with the first region in a plane of a layer face of the insulating layer; a gate electrode provided on the first region; a gate insulating film including a first part provided on the gate electrode; an oxide layer including a first portion and a second portion, the first portion being provided on the first part and including a source region, a drain region apart from the source region in a plane parallel to the layer face, and a middle region provided between the source region and the drain region, the middle region having a first electric resistance, the second portion being provided on the second region and having a second electric resistance lower than the first electric resistance, the second portion serving as a pixel electrode; a source electrode provided on the source region and electrically connected with the source region; a drain electrode provided on the drain region and electrically connected with the drain region, one of the source electrode or the drain electrode being electrically connected with the second portion; a channel protecting layer provided on the middle region; a passivation film covering the source electrode, the drain electrode, and the channel protecting layer; and an optical element provided on the second portion and configured to produce at least one of a change in optical characteristics or light emitting by an electric signal provided to the pixel electrode, the method comprising: forming the gate electrode on the first region; forming the gate insulating film on the gate electrode and on the second region; forming the oxide layer on the gate insulating film to form the first portion and the second portion; forming the channel protecting layer on the middle region; forming the source electrode on the source region and forming the drain electrode on the drain region; forming the passivation film covering the source electrode, the drain electrode, the channel protecting layer, and the second portion; removing a part of the passivation film covering the second portion; and forming the optical element on the second portion.
