    Abstract: A display device includes a driving substrate, multiple light-emitting elements, first and second transparent substrates, multiple pixels, and a patterned light-absorbing layer. The light-emitting elements are disposed on the driving substrate and used to emit a light. The first transparent substrate is disposed over the driving substrate and the light-emitting elements and includes at least one groove. The pixels are disposed in the groove and include a first sub-pixel, a second sub-pixel, and a third sub-pixel respectively aligned with one of the light-emitting elements. The second transparent substrate covers the first transparent substrate and the pixels. The patterned light-absorbing layer is disposed on the second transparent substrate and includes multiple first openings respectively aligned with the first, second, and third sub-pixels. The first, second, and third sub-pixels correspond to the light emitted by the light-emitting elements to respectively emit a red light, a green light, and a blue light.
