Display device and electronic device including the same including signal transmission region

A display device in which a signal transmission region, a peripheral region surrounding at least a portion of the signal transmission region, and a display region adjacent to the peripheral region are defined, the display device comprising:

• a plurality of light-emitting elements disposed in the display region;
• a pixel defining film in which a plurality of light-emitting openings in which the plurality of light-emitting elements is disposed respectively is defined;
• and
• a dam surrounding the signal transmission region and disposed in the peripheral region, the dam comprising:
• a spacer disposed on the pixel defining film,
• wherein a hole is defined in the signal transmission region,
• a portion of the pixel defining film is disposed in the peripheral region, and
• a first opening defined in the peripheral region and adjacent to the dam is defined in the portion, disposed in the peripheral region, of the pixel defining film, wherein
• the peripheral region comprises an intermediate region which is a region between the display region and an opening region in which the first opening is defined, and
• the spacer is not disposed in the intermediate region.

An electronic device comprising:

• a display device in which a signal transmission region, a peripheral region surrounding at least a portion of the signal transmission region, and a display region adjacent to the peripheral region are defined, the display device comprising;
• a base layer;
• a circuit layer disposed on the base layer;
• a light-emitting element layer disposed on the circuit layer and including:
• a plurality of light-emitting elements disposed in the display region;
• a pixel defining film in which a plurality of light-emitting openings in which the plurality of light-emitting elements is disposed respectively is defined;
• and
• a spacer disposed on the pixel defining film, the spacer including a first spacer disposed between the signal transmission region and an opening region in which a first opening is defined;
• and
• an electronic module overlapping the signal transmission region,
• wherein
• a hole is defined in the signal transmission region, the hole penetrating at least a portion of each of the circuit layer and the light-emitting element layer,
• a portion of the pixel defining film is disposed in the peripheral region, and
• the first opening defined in the peripheral region is defined in the portion, disposed in the peripheral region, of the pixel defining film.
