Abstract
Disclosed herein is a display including an acceptor substrate having thereon a red light-emitting element column, a green light-emitting element column, and a blue light-emitting element column that are arranged along a row direction and are each obtained by arranging rectangular organic light-emitting elements for generating light of one of red, green, and blue along a longitudinal direction of the organic light-emitting elements.
Claims6
A display including organic light-emitting elements formed on an acceptor substrate, the organic light-emitting elements including a plurality of organic red light-emitting elements arranged in a first column, a plurality of organic green light-emitting elements arranged in a second column, and a plurality of organic blue light-emitting elements arranged in a third column, the display formed by a process comprising:
- forming a donor including a transfer layer;
- forming on the acceptor substrate, for each of the organic light-emitting elements, a first electrode and an insulating layer having an aperture corresponding to a light-emission area of the first electrode;
- transferring the transfer layer to the acceptor substrate to form a light-emitting layer of an organic layer of each of the organic light-emitting elements in at least the first column and the second column;
- and
- forming a second electrode on the organic layer,
- wherein a first A point on the donor is where a tangent line of the insulating layer is drawn from a first side end of a first light-emission area to intersect with the donor, a first C point over the insulating layer is at first A Point or vertically below first A point over an upper surface of the insulating layer, and the light-emitting layer is formed over the insulating layer to cover at least first C point designated over the insulating layer, and
- wherein a contact area between the insulating layer and the donor in the third column that includes the organic blue light-emitting elements is larger than contact area in the first column that includes the organic red light-emitting elements and the contact area in the second column that includes the organic green light-emitting elements.
