  • Publication number: 20090225050
    Abstract: The present invention is configured such that a touch panel has a dot spacer that is disposed on an inner transparent conductive film and that is disposed on a display surface of a liquid crystal display panel via an air layer. An another dot spacer is disposed on a surface of touch panel opposite to the display surface of the liquid crystal display panel at a position which does not overlap with the dot spacer within a predetermined view angle range on the display surface.

  • Patent number: 7193679
    Abstract: A method of fabricating a substrate for a display device prevents the problems occurring in the pattering process of a photosensitive organic material layer, such as the “stage image transfer” and “mask image reflection”. A photosensitive organic material layer is formed on or over a transparent plate, the layer being divided into a display section and a terminal section located outside the display section. The photosensitive organic material layer has a first thickness in the display section and a second thickness different from the first thickness in the terminal section. The layer is exposed to exposing light in such a way that the layer in the display section is exposed at a first exposure value according to the first thickness and the layer in the terminal section is exposed at a second exposure value according to the second thickness.
