  • Patent number: 8467127
    Abstract: A screen has an incidence plane that reflects a projected light, and, on the incidence plane, a plurality of lens elements are arranged. The plurality of lens elements have quarter-spherical surfaces, and the spherical surfaces are formed so as to face a light source of the projected light. In a portion of the spherical surface, the portion onto which the projected light is projected, a reflecting section that reflects the projected light is formed. This makes it possible to increase the area of the reflecting sections in the incidence plane and thereby increase the brightness of the screen.

  • Patent number: 8120248
    Abstract: A light-emitting device includes a substrate, and a light-emitting element including a lower electrode, a light-emitting function layer, and an upper electrode that are formed on the substrate in that order. At least one auxiliary electrode in a strip shape extends in a first direction on and in contact with the upper electrode. The auxiliary electrode has a cross section taken along the direction intersecting the first direction, having a shape including a tapered portion. The light-emitting device also includes a barrier layer covering the auxiliary electrode and the upper electrode. The barrier layer prevents water and oxygen from penetrating into the light-emitting element.
