Display device and electronic device, and method of driving display device

A method of driving a display device which comprises a first pixel and a second pixel disposed in each of unit areas of a display area and sharing one subpixel, the method comprising:

• displaying an image of each frame by driving the first pixel disposed in the unit areas in response to a first emission mode;
• displaying an image of each frame by driving at least some of the second pixel disposed in the unit areas in response to a second emission mode;
• and
• displaying an image of each frame by alternately driving the first pixel and the second pixel disposed in the unit areas in response to a third emission mode.

An electronic device comprising:

• a display device comprising:
• a first pixel and a second pixel disposed in a first unit area of a display area comprising unit areas, each of the first pixel and the second pixel comprising a first subpixel and a second subpixel, and the first pixel and the second pixel sharing a third subpixel;
• a first light blocking layer disposed on a light emitting element layer which comprises light emitting elements of subpixels disposed in each of the unit areas and surrounding emission areas in which the light emitting elements are disposed;
• and
• a second light blocking layer disposed on the first light blocking layer and surrounding emission areas of the first subpixel and the second subpixel of the second pixel in the first unit area,
• wherein the first pixel and the second pixel are driven in different periods.
