1. A display device comprising:
a window;
a display panel comprising a first display area and a second display area having a pixel density less than that of the first display area, the display panel being under the window;
a protective layer under the display panel; and
a lower layer in which a first opening corresponding to the second display area is defined and which is under the protective layer,
wherein a portion of the protective layer, which corresponds to the second display area, has a haze of 4% or less, a wavefront peak valley value of 0.05 or more and 2.00 or less, a wavefront root mean square value of 0.01 or more and 0.40 or less.
 
13. A display device comprising:
a window;
a display panel comprising a first display area and a second display area having a pixel density less than that of the first display area, the display panel being under the window;
a protective layer under the display panel; and
a lower layer in which a first opening corresponding to the second display area is defined and which is under the protective layer,
wherein the protective layer comprises:
a synthetic resin film corresponding to the first display area and in which a second opening corresponding to the second display area is defined; and
a synthetic resin layer inside the second opening,
wherein the synthetic resin layer has an elastic modulus less than that of the synthetic resin film, and
the synthetic resin layer has a haze less than that of the synthetic resin film,
wherein the synthetic resin layer has a wavefront peak valley value of 0.05 or more and 2.00 or less.
 
19. An electronic device comprising:
a display device comprising a first display area and a second display area having a pixel density less than that of the first display area;
a camera module under the display device to correspond to the second display area; and
a housing coupled to the display device to accommodate the camera module,
wherein a modulation transfer function value of an image of a subject outside the display device, which is photographed by the camera module is 60% or more at a frequency of 110 LP/mm, and
a protective layer in a path along which light reflected from the subject is incident into the camera module has a haze of 4% or less and a wavefront peak valley value of 0.05 or more and 2.00 or less.
