  • Publication number: 20080170047
    Abstract: In a liquid crystal display device having a liquid crystal display panel, the liquid crystal display panel includes a display section having a plurality of pixels disposed therein and a peripheral section disposed so as to surround the display section. A display corresponding to a touch key is displayed on the display section at a boundary portion between the display section of the liquid crystal display panel and the peripheral section adjoining thereto. A photosensor for detecting light is disposed at a portion in the peripheral section near the display corresponding to the touch key. In this liquid crystal display device, the photosensor produces an output of a current value detected as a result of all or part of external light being shielded when a viewer touches the display corresponding to the touch key on the display section.

  • Publication number: 20080044983
    Abstract: A support-side substrate having a thermal oxide film on the major surface is bonded to an active-layer-side substrate having a thermal oxide film on the major surface while making the major surfaces oppose each other. The active-layer-side substrate and part of the oxide film are selectively etched from a surface opposite to the major surface of the active-layer-side substrate to a halfway depth of the buried oxide film formed from the thermal oxide films at the bonding portion. A sidewall insulating film is formed on the etching side surface portion of the active-layer-side substrate. Then, the remaining buried oxide film except that immediately under the active-layer-side substrate is selectively etched. A single-crystal semiconductor layer is formed on the support-side substrate exposed by removing the buried oxide film.
