  • Patent number: 7989805
    Abstract: An electronic device of the present invention includes a first substrate provided with a thin film active element, having a thickness of 200 ?m or lower, and a second substrate formed with a high thermal conductivity portion. The second substrate is applied to one surface of the two surfaces of the first substrate, i.e., the surface being the side other than the side that formed with the thin film active element. The thin film active element has a maximum power consumption of 0.01 to 1 mW. The high thermal conductivity portion is a region that corresponds to the position of the thin film active element and whose thermal conductivity falls within the range from 0.1 to 4 W/cm·deg.

  • Patent number: 7450198
    Abstract: A reflection-type liquid crystal display according to the invention includes two glass substrates, a transparent electrode provided on one glass substrate, an insulator film which is provided on another glass substrate and on which an uneven structure is formed, a reflecting electrode provided on the insulator film, and a liquid crystal layer sandwiched between a side of the transparent electrode and a side of the reflecting electrode. The insulator film includes a first insulating layer in which a large number of depressions isolated as surrounded by protrusions are irregularly arranged and a second insulating layer covering the insulating layer entirely. The protrusions are all connected in a network, so that if some of these protrusions have weaker adherence with an underlying layer, they can be supported by the surrounding protrusions.

  • Patent number: 6891196
    Abstract: An active matrix substrate of a channel protection type having a gate electrode, a drain electrode and a pixel electrode is isolated in each layer by insulating films. The active matrix substrate is to be prepared by four masks. A gate electrode layer, a gate insulating film and an a-Si layer are processed to the same shape on a transparent insulating substrate to form a gate electrode layer and a TFF area. A drain electrode layer is formed by a first passivation film with the first passivation film formed as an upper layer. In a second passivation film, formed above the first passivation film, are bored a first opening through the first and second passivation films and a second opening through the second passivation film. A wiring connection layer is formed by ITO provided as an uppermost layer.
