Abstract
A display device, including a display region formed of a plurality of pixels, and a terminal region formed on an outer side of the display region, includes a terminal wiring formed in the terminal region, a pixel wiring formed in each of the plurality of pixels, an insulating film, which is formed in the terminal region on an upper layer of the terminal wiring, and is formed in the display region on an upper layer of the pixel wiring, and a preventing film formed in the terminal region on an upper layer of the insulating film. The terminal wiring is exposed in an electrical connection region of the terminal region.
Claims11
A display device, including a display region formed of a plurality of pixels, and a terminal region formed on an outer side of the display region, comprising:
- a terminal wiring formed in the terminal region;
- a pixel wiring formed in each of the plurality of pixels;
- an insulating film, which is formed in the terminal region on an upper layer of the terminal wiring, and is formed in the display region on an upper layer of the pixel wiring;
- and
- a preventing film formed in the terminal region on an upper layer of the insulating film,
- the terminal wiring being exposed in an electrical connection region of the terminal region.
A method of manufacturing a display device, including a display region formed of a plurality of pixels, and a terminal region formed on an outer side of the display region, comprising:
- forming a terminal wiring in the terminal region;
- forming a pixel wiring in each of the plurality of pixels;
- forming, in a region other than an electrical connection region of the terminal region, an insulating film on an upper layer of the pixel wiring, and a preventing film on an upper layer of the insulating film;
- forming a sealing film so as to cover an entire surface of the display region and the terminal region;
- and
- etching the sealing film formed in the terminal region, to thereby expose the terminal wiring in the electrical connection region,
- the sealing film being formed of a material having a high etching selectivity ratio to the preventing film.
