Abstract:
1. An organic electroluminescent device, comprising: a first substrate including a first pixel region, the first pixel region including first, second and third sub-pixel regions having substantially the same size; an array element layer on an inner surface of the first substrate, the array element layer including a thin film transistor in each sub-pixel region; a second substrate facing the first substrate and being spaced apart from the first substrate, the second substrate including a second pixel region corresponding to the first pixel region, and the second pixel region including fourth, fifth and sixth sub-pixel regions; an organic electroluminescent diode on an inner surface of the second substrate in each sub-pixel region; and a connection electrode electrically connecting the first substrate to the second substrates, wherein the fourth, fifth and sixth sub-pixel regions have different sizes from each other, wherein the connection electrode connects a second electrode and a thin film transistor in each sub-pixel region, and wherein the thin film transistor includes a switching thin film transistor and a driving thin film transistor in each sub-pixel region, and the driving thin film transistor is substantially connected to the second electrode.
