The display device 1000 may include first pixels P in the first display area DA1. Each of the first pixels P may emit light. For example, the first pixels P may include a red-pixel emitting red light, a green-pixel emitting green light, and a blue-pixel emitting blue light.

In the second display area DA2, a light block layer 200 may be disposed on the functional module 100. The light block layer 200 may block external light incident from an outside of the display device 1000. For example, the light block layer 200 may include a metal having a low light transmittance. The light block layer 200 may include patterns (or unit patterns) 210. For example, the unit patterns 210 may be arranged or disposed in a matrix form.

The light block layer 200 may overlap a part of the functional module 100. Accordingly, the second display area DA2 may include a transmission area TA as an area in the second display area DA2 in which the light block layer 200 does not exist. In the transmission area TA, the external light may be incident on the functional module 100.

FIG. 3 is a schematic plan view illustrating an example of a unit pattern included in the light block layer of FIG. 2. FIG. 4 is a schematic plan view illustrating an example of a unit pattern included in the light block layer of FIG. 2.
