  • Publication number: 20140042928
    Abstract: A light-emitting device includes a plurality of organic EL elements including first electrodes, a second electrode, and organic compound layers therebetween, pixel circuits connected to the corresponding first electrodes, and a common power supply connected to the second electrode, in which at least a part of the organic compound layers is formed to extend from over the plurality of first electrodes to gap areas between the first electrodes, and a resistance between two adjacent first electrodes is less than a resistance between one of the first electrodes and the second electrode. Each of the organic EL elements receives an intermittent supply of a current from the corresponding pixel circuit, and during a period in which the current is stopped, a voltage equal to or less than a light emission threshold value is applied to the organic EL element.

  • Patent number: 6952249
    Abstract: In a liquid crystal display having liquid crystal sealed between first and second substrates opposing one another, the first substrate is provided with data lines (56) formed overlapping pixel electrodes (58). By forming color filters (1) in a layer between the data lines (56) and the pixel electrodes (58), the distance between the data lines (56) and the pixel electrodes (58) is increased, reducing parasitic capacitance generated therebetween. Effective voltage application to the pixel electrodes (58) is thereby accomplished, allowing increase in contrast. No decrease in transmittance is caused because the thickness of the planarizing film (2) is not increased.

  • Patent number: 6827622
    Abstract: A glass substrate is placed within a vacuum chamber with the surface on which an emissive layer forming an electroluminescence element is to be formed by evaporation facing downward. A mask is disposed within the vacuum chamber. A material of the emissive layer is adhered to the glass substrate through an opening of the mask, to thereby form the emissive layer. When the glass substrate and the mask are aligned, at least three sides of the glass substrate are supported by side supporting members.

  • Patent number: 6597423
    Abstract: A pixel electrode (55) and a common electrode (63) having alignment control windows (65) formed thereon, are formed on opposing substrates (50, 60). Alignment control assistance electrodes (1) are formed between the substrate (60) and a color filter (61) in areas covering the alignment control windows (65), and supplied with a voltage of a different polarity from that to be applied to the opposing pixel electrodes. With this arrangement, an electric field is formed in areas with the alignment control window formed thereon, whereby an alignment direction of the liquid crystal molecules is more strongly controlled.

  • Publication number: 20030017258
    Abstract: In manufacturing an electroluminescence display apparatus, after a substrate and a mask disposed below the substrate are aligned with each other, a material of an electroluminescence element is adhered to the substrate through an opening of the mask to form an electroluminescence element layer. Alignment of the substrate and the mask is performed while an upper surface of the substrate is supported by adsorption. Because the substrate is supported by adsorption during the alignment of the substrate and the mask, the flexure in the substrate can be inhibited. When a plurality of pins are provided on the mask side or the sides of the substrate are further supported by side supporting members, occurrence of flexure in the substrate can be more reliably inhibited.

  • Patent number: 6323924
    Abstract: A liquid crystal display device has a liquid crystal layer formed between first and second insulating substrates. A wiring layer, an insulation film and a first orientation layer are formed on the first substrate between it and the liquid crystal layer. A electrode layer and a second orientation film are formed on the second substrate between it and the liquid crystal layer. The wiring layer includes grooves along its peripheral portion which allow the insulation film to contact the first substrate, which promotes bonding and inhibits peeling of the insulation film from the wiring layer.

  • Patent number: 6008874
    Abstract: An active matrix liquid crystal display improves its contrast by suppressing irregularity of an alignment film caused by video lines thereby reducing reverse regions on a display electrode. The active matrix liquid crystal display has first and second opposite substrates, a video line, an active element and a display electrode which are directly or indirectly formed on the first substrate, and an alignment film which is formed on or above the video line, the active element and the display electrode. The alignment film is so formed that is surface is at an angle of inclination of not more than 10.5.degree. with respect to the display electrode surface between the video line and the display electrode.
