Abstract: A display panel includes: a window including a display area, and a non-display area adjacent to the display area; a color filter layer on the window; a circuit element layer including: a low refractive index layer covering the color filter layer; and a transistor on the low refractive index layer; a light control layer including: division partition walls on the circuit element layer; and a light control pattern between the division partition walls, and including quantum dots; and a display element layer on the light control layer, and including: a first electrode; a second electrode on the first electrode; and an emission layer between the first electrode and the second electrode and to generate light. The light passes through the light control layer, the circuit element layer, and the color filter layer to be transmitted to the window.

Abstract: A display panel includes a circuit board and an element layer disposed on the circuit board and including a pixel defining layer having a plurality of openings, and a spacer disposed on the pixel defining layer. The plurality of openings include a first opening, a second opening, and a third opening that are adjacent to the spacer. The spacer includes a central portion disposed between the first, second, and third openings and a first extension, a second extension, and a third extension that protrude from the central portion in three directions, respectively. End portions of the first, second, and third extensions are disposed in a region defined by virtual lines connecting a first center of the first opening, a second center of the second opening, and a third center of the third opening.
