ABSTRACT:
An organic light emitting device according to an embodiment includes a thin film transistor substrate including a plurality of thin film transistors and an over-coating film formed on the thin film transistors. The over-coating film includes a curved surface on at least two pixels among pixels of different colors and the slope angles of depressed portions forming the curved surface are respectively different from each other depending on the colors of the pixels. A plurality of first electrodes formed on the over-coating film includes a surface formed according to the curved surface, an organic light emitting member formed on the first electrodes includes a surface formed according to the curved surface, and a second electrode formed on the organic light emitting member includes a surface formed according to the curved surface. Slope angles of the depressed portions increase according to a decrease of wavelengths of the colors of the pixels.
