Abstract
Disclosed herein is a display panel including a polarizing emission layer. An organic light emitting device is formed on a first substrate. A polarizing emission layer are formed on a second substrate facing the first substrate. The polarizing emission layer is formed in a subpixel area corresponding to the organic light emitting device. The polarizing emission layer includes quantum rods. The quantum rods are aligned in one direction to be polarized. Accordingly, loss of transmitting light in the display panel including the polarizing layer may be minimized. In addition, since colors are implemented by the quantum rods included in the polarizing emission layer, color filters can be replaced by the quantum rods, and loss of light resulting from the color filters may be minimized.
