Abstract
A display device includes: a photo sensor layer to receive light reflected from an external object; a substrate on the photo sensor layer; an optical pattern layer on the substrate, the optical pattern layer including a light blocking portion, and a light transmitting portion corresponding to an opening penetrating the light blocking portion in one direction; an optical filter in the light transmitting portion of the optical pattern layer; and a light emitting device layer on the optical pattern layer.
Claims20
A display device comprising:
- a photo sensor layer configured to receive light reflected from an external object;
- a substrate on the photo sensor layer;
- an optical pattern layer on the substrate, the optical pattern layer comprising a light blocking portion, and a light transmitting portion corresponding to an opening penetrating the light blocking portion in one direction;
- an optical filter in the light transmitting portion of the optical pattern layer;
- and
- a light emitting device layer on the optical pattern layer.

A method of manufacturing a display device, the method comprising:
- coating a light blocking material on a substrate;
- forming an optical pattern layer by patterning the light blocking material, the optical pattern layer comprising a light blocking portion, and a light transmitting portion corresponding to an opening penetrating the light blocking portion in one direction;
- alternately stacking a first filter layer having a first refractive index and a second filter layer having a second refractive index on the light blocking portion and the light transmitting portion;
- forming an optical filter by repeating the stacking of the first filter layer and the second filter layer;
- polishing a top surface of the optical filter;
- and
- providing a display panel including a light emitting device layer on the substrate on which the optical pattern layer and the optical filter are formed.
