Abstract:
1. A display device comprising: a substrate that comprises first, second, and third subpixel regions; first, second, and third organic light-emitting transistors disposed in the first, second, and third subpixel regions, respectively, and operable to emit light of a first color, at least one of the first, second, and third organic light-emitting transistors including a bulk heterojunction structure, the bulk heterojunction structure comprising an n-type organic semiconductor that is configured to emit a blue light; and a first fluorescent pattern formed on the first organic light-emitting transistor and operable to cause light of a second color to be emitted, the first fluorescent pattern at least partially covering the first organic light-emitting transistor in a layout view of the display device and exposing a portion of the first organic light-emitting transistor in the layout view of the display device.
