Display device and method of manufacturing the same

A display device comprising:

• a base layer;
• a circuit layer on the base layer;
• and
• an element layer on the circuit layer and comprising light-emitting elements and light-receiving elements, the element layer comprising:
• a pixel definition layer defining a light-emitting opening defined therethrough to correspond to the light-emitting elements, and a light-receiving opening defined therethrough to correspond to the light-receiving elements;
• a disconnected spacer layer adjacent to the light-receiving opening on the pixel definition layer;
• and
• a common layer commonly in the light-emitting elements and the light-receiving elements, and partially disconnected around the light-receiving elements due to the disconnected spacer layer,
• wherein the pixel definition layer comprises:
• sub-sidewalls defining the light-receiving opening;
• and
• corner portions defined by two sub-sidewalls connected to each other and adjacent to each other among the sub-sidewalls, and
• wherein the disconnected spacer layer comprises disconnected spacers respectively adjacent to the sub-sidewalls.
