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.
