Abstract
The present application discloses a display device having a metal pattern on a substrate of a display device and a light absorbing layer positioned to absorb light reflected by the metal pattern, and a manufacturing method thereof. The light absorbing layer has a pattern corresponding to at least a portion of the metal pattern.
Claims20
A display device, comprising:
- a first substrate;
- a metal pattern on the first substrate, the first substrate including multiple surfaces with a first main surface, the first main surface being closest of the multiple surfaces to the metal pattern;
- a transparent electrode;
- a switching transistor for driving image display and comprising a drain electrode;
- a first light absorbing layer positioned to absorb light reflected by the metal pattern;
- a first quarter wave plate;
- and
- a first half wave plate;
- wherein the transparent electrode is electrically connected to the drain electrode of the switching transistor;
- the first light absorbing layer has a pattern corresponding to at least a portion of the metal pattern, an orthographic projection of the first light absorbing layer in plan view of the first substrate on the first main surface is at least partially non-overlapping with an orthographic projection of the transparent electrode in plan view of the first substrate on the first main surface;
- and
- the first quarter wave plate and the first half wave plate are so positioned that light reflected by the metal pattern passes through the first quarter wave plate and the first half wave plate in a sequential order before it is absorbed by the first light absorbing layer, wherein the first substrate is a substrate proximal to a first light emitting surface of the display device for image display.
