Display panel and display apparatus including component and transmission areas

A display panel including a main display area, a component area including a transmission area, and a peripheral area outside the main display area, the display panel comprising:

• a substrate;
• an inorganic insulating layer over the substrate and including a first hole corresponding to the transmission area;
• a pixel definition layer arranged over the inorganic insulating layer and having a thickness of 1.3 μm to 2 μm;
• and
• a thin film encapsulation layer over the pixel definition layer and including a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer,
• wherein the organic encapsulation layer includes a concave portion or a convex portion.

A display apparatus comprising:

• a display panel including a main display area, a component area including a transmission area, and a peripheral area outside the main display area;
• and
• a component under the display panel to correspond to the component area,
• the display panel comprising:
• a substrate;
• an inorganic insulating layer over the substrate and including a first hole corresponding to the transmission area;
• a planarization layer over the inorganic insulating layer;
• a pixel definition layer over the planarization layer and having a thickness of 1.3 μm to 2 μm;
• and
• a thin film encapsulation layer over the pixel definition layer,
• wherein an angle between a side surface of the pixel definition layer and an upper surface of the planarization layer is 30 degrees to 40 degrees.
