Display apparatus including light-condensing layer on sensor electrode layer and method of manufacturing the same

A display apparatus comprising:

• a first pixel electrode and a second pixel electrode apart from each other in a first direction;
• a pixel-defining layer covering edges of each of the first pixel electrode and the second pixel electrode, wherein a first opening is defined through the pixel-defining layer to expose a central portion of the first pixel electrode, and a second opening is defined through the pixel-defining layer to expose a central portion of the second pixel electrode;
• a first light-condensing layer disposed over the first pixel electrode to correspond to the first opening, wherein a first first slope angle of a first first side surface of the first light-condensing layer with respect to a lower surface of the first light-condensing layer is different from a second first slope angle of a second first side surface of the first light-condensing layer with respect to the lower surface of the first light-condensing layer, and the second first side surface is opposite to the first first side surface in the first direction;
• and
• a second light-condensing layer disposed over the second pixel electrode to correspond to the second opening, wherein a first second slope angle of a first second side surface of the second light-condensing layer with respect to a lower surface of the second light-condensing layer is different from a second second slope angle of a second second side surface of the second light-condensing layer in a direction to the second first side surface with respect to the lower surface of the second light-condensing layer, and the second second side surface is opposite to the first second side surface in the first direction,
• wherein each of the first first slope angle and the second second slope angle is equal to or greater than about 70° and less than about 80°, and
• wherein each of the first second slope angle and the second first slope angle is equal to or greater than about 50° and less than about 70°.
