  • Patent number: 8093803
    Abstract: An electro-optical device includes a substrate, a partition disposed on the substrate, and a plurality of electro-optical elements disposed on the substrate. Each element includes a functional layer having an electro-optic function, with a resolution in a first direction that corresponds to an interval between the elements in the first direction. The plurality of elements constitute element arrays and are divided into a plurality of element groups. The element arrays are arranged in a direction crossing the first direction. Each group includes the corresponding electro-optical elements aligned in a second direction crossing the first direction, and each of the plurality of element regions includes at least one of the element groups and extends in a third direction crossing the first direction as viewed from the top.
    Type: Grant

  • Patent number: 7884541
    Abstract: An organic electroluminescent apparatus includes a plurality of light-emitting elements each having an organic layer held between a pixel electrode and a counter electrode, and a partition pattern with which the organic layers of the individual light-emitting elements are defined. The partition pattern has a plurality of openings in which the organic layers are respectively provided, the plurality of openings including first openings provided in a peripheral region of a element area, in which the light-emitting elements are arranged, and second openings provided in a region closer to the center of the element area than the region where the first openings are provided. The first openings have larger planar dimensions than those of the second openings.
