Abstract: A lighting apparatus has improved aperture ratio by changing auxiliary lines in a lattice shape into a line shape. In addition, a conductive layer having a high resistance is formed on the entire surface to control excessive current due to a short circuit, and an island-shaped anode is formed in the emission zone to reduce the resistance in the pixel, thereby preventing the luminance from being lowered.

Abstract: The present disclosure relates to an electroluminescent lighting device embedding touch function. The present disclosure provides an electroluminescent light device that includes a substrate including an emission area and a non-emission area surrounding the emission area. An emission element is disposed on a first surface of the substrate in the emission area. A first pad and a second pad are disposed on the first surface of the substrate in the non-emission layer. A touch layer is disposed on a second surface of the substrate opposite the first surface, and a cover plate is attached on a bottom surface of the touch layer.

Abstract: A lighting apparatus of the present disclosure includes an organic light emitting diode formed by a first electrode, an organic light emitting layer, and a second electrode on a first substrate and configures the first electrode by a transparent conductive material having an electrical resistance of 2800 to 5500Ω in each pixel. Therefore, even though the first electrode and the second electrode are in contact with each other to remove the electrical resistance by the organic light emitting layer in the pixel, the overcurrent is suppressed from being applied to the pixel by the electrical resistance of the first electrode. Further, at least one conductive pattern formed of a low electrical resistance transparent conductive material which is connected to the first electrode in the pixel is disposed to suppress the degradation of the luminance by the first electrode having a high electrical resistance.
