Display device, manufacturing method thereof, and manufacturing apparatus thereof

A display device comprising:

• a display panel, including:
• a display region including a plurality of pixels;
• a non-display region around the display region;
• and
• a first indicia and a second indicia disposed in the non-display region, the first indicia and the second indicia separated and spaced apart from each other when viewed in a plan view;
• and
• a window disposed on the display panel and, including:
• a transmission region overlapping the display region;
• a light blocking region overlapping the non-display region;
• and
• a third indicia disposed in the light blocking region;
• wherein when viewed in a plan view, the third indicia disposed in the light blocking region does not overlap with the first indicia and the second indicia separated from each other in the non-display region;
• wherein at least one of the pixels comprises:
• a transistor disposed on a substrate and including a gate electrode, a source electrode, and a drain electrode, and a semiconductor layer;
• and
• a light emitting element connected to the transistor,
• wherein the first indicia is formed of the same material as the gate electrode and disposed on the same layer as the gate electrode, and
• wherein the second indicia is formed of the same material as the semiconductor layer and disposed on the same layer as the semiconductor layer.

A display device defining a longitudinal direction, a width direction perpendicular to the longitudinal direction, and a thickness direction perpendicular to the longitudinal and width directions, and comprising:

• a display panel, including:
• a display region;
• a non-display region around the display region;
• and
• a first indicia and a second indicia disposed in the non-display region, the first indicia and the second indicia separated and spaced apart from each other when viewed in a plan view;
• and
• a window disposed on the display panel and, including:
• a transmission region overlapping the display region;
• a light blocking region overlapping the non-display region;
• and
• a third indicia disposed in the light blocking region;
• wherein, when viewed in a plan view, the third indicia is disposed at an outer periphery spaced apart from an edge of the display panel,
• wherein when viewed in a plan view, the third indicia disposed in the light blocking region does not overlap with the first indicia and the second indicia separated from each other in the non-display region, and
• wherein the third indicia does not overlap the display panel in the thickness direction.
