Abstract:
1. An organic light emitting display device, comprising: a substrate; and a plurality of pixels, each pixel including: a protrusion pattern and a trench area formed in the substrate, the protrusion pattern having a first height, and the trench area being formed in an area of the substrate except for the protrusion pattern and having a second height lower than the first height; an organic light emitting device disposed on the substrate; a capacitor, the capacitor including a first capacitor electrode and a second capacitor electrode; a first transistor, the first transistor being coupled to a gate line extended in a row direction, a data line extended in a column direction crossing the row direction, and the first capacitor electrode; and a second transistor, the second transistor being coupled to the first capacitor electrode, a voltage line extended in the column direction, and the organic light emitting device, wherein the second capacitor electrode is branched from the voltage line, and the gate line and the first capacitor electrode are formed on and overlap the protrusion pattern.
