  • Patent number: 11018200
    Abstract: A display device including color filters overlapping each other on a non-emitting area of an upper substrate which is opposite to a lower substrate is provided. In the display device, color filters disposed close to a white emitting area include a same material, and the color filters extend a greater distance onto a non-emitting area disposed near the white emitting area, relative to distances extended onto other non-emitting areas. Thus, the display device may prevent light-leakage from the white emitting area.

  • Patent number: 10720480
    Abstract: A display device serving as a mirror in a non-display state is provided. The display device may include a reflective pattern and a half-mirror layer which are disposed on an upper substrate opposite to a lower substrate. The half-mirror layer may be disposed side by side with the reflective pattern. Thereby, a discontinuous appearance of the reflective image may be reduced, and the degradation of the reflective image due to the diffraction of the light may be prevented or reduced.

  • Patent number: 10686160
    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.

  • Patent number: 10591787
    Abstract: A display device including an auxiliary electrode in order to prevent the luminance unevenness is provided. In the display device, an under-cut region may be formed by a first penetrating hole of a lower passivation layer and a second penetrating hole of an over-coat layer in order to connect an upper electrode to the auxiliary electrode. The second penetrating hole of the over-coat layer may be disposed to be offset from the first penetrating hole of the lower passivation layer, so that the under-cut region may be partially broken in an edge of the auxiliary electrode. Thus, the display device may improve the reliability of the electrical connection between the auxiliary electrode and the upper electrode.
