Abstract:
1. An OLED display device having a built-in touch panel comprising: an upper substrate and a lower substrate arranged opposite to each other; a thin film transistor array on the lower substrate; an organic light emitting array on the thin film transistor array; a flattening film formed on the organic light emitting array; a touch sensor array on the upper substrate opposite to the lower substrate for sensing external touch by a capacitive type; an adhesive film formed between the organic light emitting array and the touch sensor array; an upper contact pad formed on an outer region of the upper substrate and connected to the touch sensor array; a lower contact pad formed on an outer region of the lower substrate opposite to the upper contact pad; a conductive spacer connected between the upper contact pad and the lower contact pad; and a signal transmission film electrically connected to a main pad on the lower substrate and supplying signals that control the thin film transistor array and the touch sensor array, wherein the lower contact pad is on one side of the outer region of the lower substrate, and the main pad is on another side of the outer region of the lower substrate and electrically connected to the lower contact pad with a connection line which is formed on the lower substrate, wherein the touch sensor array includes a plurality of X electrodes, a first insulating film formed on the X electrodes, a plurality of Y electrodes formed on the first insulating film, and a second insulating film formed on the Y electrodes, wherein a top surface of the flattening film and a top surface of the second insulating film are flat and opposite to each other, wherein a space between the flattening film and the second insulating film is filled with the adhesive film, so that the flattening film and the second insulating film are directly face sealed by the adhesive film, and wherein the adhesive film is formed of an insulating material and covers at least the flattening film and side surfaces of the organic light emitting array.
