    Abstract: In EL display panels fabricated by vapor deposition, a vapor-deposition fine mask is employed to form red, green, and blue pixels. An issue, however, has been that misregistration of the vapor-deposition fine mask occurs, lowering manufacturing yields. To resolve this issue, on a thin-film transistor (TFT) substrate, red, green, and blue pixel electrodes are fashioned in matrix form. The TFT substrate is conveyed into a vapor-deposition chamber. Under a vacuum, an organic evaporation source is employed to codeposit a light-emitting layer composed of a host material and a red guest material on the TFT substrate display screen. An ultraviolet laser beam generated by a laser device is optically guided into the vapor-deposition chamber through a laser window and directed on the light-emitting layer formed onto the green and blue pixel electrodes. Positional selecting on the green and blue pixels is carried out by controlling a mirror galvanometer.

    Abstract: A display device may include a display panel including a first substrate, a second substrate on the first substrate, and a light-emitting device between the first substrate and the second substrate, an input sensing portion including a sensing electrode on the second substrate and a first pad connected to the sensing electrode, a first circuit film near a side surface of the display panel adjacent to the first pad, the first circuit film including a first contact pad spaced from the first pad, a first conductive layer on the first pad, the first conductive layer being extended to the first contact pad to electrically connect the first pad to the first contact pad, and a protection layer on the first conductive layer.
