    Abstract: PROBLEM TO BE SOLVED: To provide light emitting elements in which no cross talk is caused and light emission is conducted by a very low driving voltage in an atmospheric pressure environment and to provide a field emission display having the elements. SOLUTION: When a pulse voltage is applied to a driving electrode 4, electric field is concentrated in the vicinity of a slit and an electric field discharging phenomenon is generated. Discharged electrons hit a stimulable phosphor layer 8 through an electrically conductive coating layer 6 and an electron passing layer 7 by applying a bias voltage to a transparent electrode 9. Thus, the layer 8 is stimulated and light emission indicated by arrow marks is generated through the electrode 9. By arranging a light emitting element 1 in a two dimensional manner, a field emission display is constituted. COPYRIGHT: (C)2004,JPO

    Abstract: PURPOSE:To improve the luminous efficacy by making the thickness of a coat composed of metal oxide thicker in the circumferential inner side of a bulb disposed along the circumferential direction than the outer side thereof. CONSTITUTION:The film thickness of a coat 10 of metal oxide is formed in such a manner that the film thickness t1 of the part situated in the outside of glass bulbs 5a, 5b, 5c is thinner than the film thickness t2 of the part situated in the inside, or t1

    Abstract: PROBLEM TO BE SOLVED: To provide an organic EL panel having high quality. SOLUTION: A glass substrate 30 and a protective material 40 for protecting an organic EL element 12 are formed by a glass material to form the organic EL panel 50 having excellent resistance to changes of temperature. Moreover, the protective material 40 and the glass substrate 30 are formed by a glass material to reduce thickness of the organic EL panel more than a case where a metallic can is used. Furthermore, a degree of freedom in selection of adhesive for bonding both of them mutually is markedly increased when compared with the case where the metallic can is used. COPYRIGHT: (C)2003,JPO
