  • Patent number: 8344390
    Abstract: The objective is to achieve an organic thin film transistor group that can be manufactured more easily and at a lower cost. Provided is a thin film active element group comprising a drive active element having a semiconductor channel layer formed in a channel region between a source electrode and a drain electrode; and a switch active element having a semiconductor channel layer formed in a channel region between a source electrode and a drain electrode, the switch active element switching the drive active element. The drive active element and the switch active element are formed to be separated from each other in a direction of a channel width such that a straight line associated with the channel region of the drive active element and a straight line associated with the channel region of the switch active element are parallel to each other.

  • Publication number: 20110227100
    Abstract: A light-emitting device comprises: a substrate; a plurality of organic electroluminescent elements provided on the substrate; and a partition defining pixel areas in each of which one of the organic EL elements is provided. The partition comprises an insulating film provided with openings each hollowly formed in an area corresponding to one of the pixel areas and a partition body provided on an opposite side of the insulating film with respect to the substrate. Each of the organic EL elements comprises a pair of electrodes and a light-emitting portion that is interposed between the electrodes and that is arranged in an area surrounded by the insulating film. The thickness of the insulating film is smaller than the thickness of the light-emitting portion.

  • Publication number: 20110018007
    Abstract: Provided is a solution for narrowing of a light emitting region, increasing of leak current at an edge of a functional layer, peeling of the functional layer, or the like caused by non-uniform thickness of the functional layer at the edges thereof. Provided is an electronic device comprising a substrate; a conductive functional layer formed on the substrate; and an edge covering layer that covers edges of the functional layer, wherein the functional layer includes a functional region that is not covered by the edge covering layer. This functional layer may include a non-functional region that is made non-functional by covering the functional layer with the edge covering layer. The edge covering layer may be adhered to the substrate by an adhesion force that is greater than an adhesion force between the substrate and the functional layer.
