Disclosed is an in-cell type organic electroluminescent device. The in-cell type organic electroluminescent device according to an embodiment of the present disclosure includes at least one OLED-driving Thin-Film Transistor (OLED driving TFT) that is formed on a substrate and drives an organic light emitting device (OLED); the OLED connected to the at least one OLED driving TFT through a first contact hole; at least one touch-sensing thin-film transistor (though sensing TFT) that is simultaneously formed with the at least one OLED driving TFT on the substrate and senses touch; and an touch electrode that is connected to the at least one touch sensing TFT through a second contact hole and does not overlap with the OLED, wherein the at least one OLED driving TFT and the at least one touch sensing TFT share a gate line.
