Abstract
This display device is provided with: a circuit substrate having a display region and a non-display region; pixel-driving TFTs for driving pixels, formed in the display region and having source electrodes and drain electrodes being spaced apart from each other on an insulating film and a first active layer formed from an oxide semiconductor, provided on the opposite side from the insulating film so as to cover a separation section between a source electrode and a drain electrode and part of the source electrode and part of the drain electrode adjacent to the separation section; and a driver circuit TFT for driving the pixel-driving TFTs, formed in the non-display region and having a second active layer formed from a non-oxide semiconductor.
Claims8
A method of manufacturing a display device including a circuit substrate having a display region having formed therein a plurality of pixels, and a non-display region provided outside a periphery of the display region, the method comprising:
- forming an insulating film in a region of the circuit substrate to be the display region;
- forming a source electrode and a drain electrode included in each of pixel-driving thin film transistors for driving the pixels such that the source electrode and the drain electrode are formed apart from each other on the insulating film;
- forming a first active layer included in each of the pixel-driving thin film transistors and made of an oxide semiconductor so as to cover a separation section between the source electrode and the drain electrode and so as to cover a portion of the source electrode and a portion of the drain electrode that are respectively adjacent to the separation section from a side thereof opposite to the insulating film;
- and
- forming a second active layer included in a driver circuit thin film transistor for driving the pixel-driving thin film transistors and made of a non-oxide semiconductor in a region to be the non-display region of the circuit substrate.
