Abstract: A partial transparent display device has a light transmitting function and a light emitting function in one area. The partial transparent display device includes a substrate, a transparent emission area, a driving emission area, and a pad part. The transparent emission area is disposed to be adjacent to one side of the substrate. The driving emission area is disposed to be adjacent to the transparent emission area and to be closer to the other side opposite to the one side. The pad part extends from the driving emission area and is disposed on the other side. The driving emission area includes driving emission pixels which are defined by scan lines, data lines, and pixel driving power supply lines. The transparent emission area includes transparent emission pixels which are defined without the scan lines, the data lines, and the pixel driving power supply lines.

Abstract: Disclosed are a divisional exposure apparatus which allows for forming a PAC layer uniformly on RGBW subpixels by a single mask process, using divisional exposure, in a large-size liquid crystal display with a COT structure, and a method of manufacturing a liquid crystal display using the same. To this end, the sum of illumination intensities at the center of an overlap region is controlled in the range of 120% to 130%, and gradually increases from 100% at the edge (boundary) of the overlap region. Accordingly, the cell gap between the RGB subpixels and the W subpixel is made uniform, thus preventing the problem of spots.
