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.
