Display device and manufacturing method thereof
Disclosed is a display device including: a plurality of pixel electrodes; a plurality of opposing electrodes located over the plurality of pixel electrodes and arranged in a stripe shape; and an EL layer sandwiched between the plurality of pixel electrodes and the plurality of opposing electrodes. The plurality of opposing electrodes is electrically independent from one another. Each of the opposing electrodes may be electrically independent from the plurality of metal films. The plurality of metal films may be electrically floating.
1. A display device comprising:
a plurality of pixel electrodes;
a first insulating film located over the plurality of pixel electrodes and covering edges of the plurality of pixel electrodes;
a plurality of opposing electrodes over the plurality of pixel electrodes and the first insulating film, the plurality of opposing electrodes being arranged in a stripe shape;
an EL layer sandwiched between the plurality of pixel electrodes and the plurality of opposing electrodes and covering the first insulating film;
a plurality of insulating structural members over and in contact with the first insulating film, the plurality of insulating structural members being each sandwiched by and in contact with two adjacent opposing electrodes; and
a plurality of metal films located over the plurality of insulating structural members and arranged in a stripe shape alternately with the plurality of opposing electrodes,
wherein the plurality of opposing electrodes is each in contact with the EL layer and electrically independent from one another and from the plurality of metal films, and
a gap is formed by the plurality of insulating structural members in a thickness direction of the plurality of pixel electrodes between one of the metal films and one of the opposing electrodes adjacent to the one of the metal films.
2. The display device according to claim 1 ,
wherein each of the plurality of opposing electrodes overlaps with multiple pixel electrodes of the plurality of pixel electrodes.
3. The display device according to claim 1 ,
wherein a width of each of the plurality of metal films is smaller than a width of each of the plurality of opposing electrodes.
4. The display device according to claim 1 , further comprising:
a second insulating film over the plurality of opposing electrodes and the plurality of metal films; and
a plurality of electrodes over the second insulating film,
wherein the plurality of electrodes is arranged in a stripe shape and intersects with the plurality of opposing electrodes and the plurality of metal films.
