Abstract: Provided is a display apparatus. The display apparatus includes: a substrate in which a plurality of sub pixels is defined; a plurality of light emitting diodes which is disposed in the plurality of sub pixels and shares an organic layer and a cathode; a bank which is disposed below the cathode between the plurality of light emitting diodes; a plurality of wiring lines disposed between the bank and the substrate; and a first pattern which is disposed in the bank and overlaps at least one of the plurality of wiring lines, and the cathode is disposed in the first pattern. Accordingly, the length of the cathode and the organic layer in the first pattern is increased so that the length of the path through which the leakage current flows is increased, which may minimize the degradation of the display quality due to the leakage current.
