Abstract: A video display device (100) includes a board (1) on which light emitters (10) to emit light are mounted and a support (2) including a support film (20) receiving the board (1). The board (1) is installable to extend in a gravitational direction. The support (2) has an opening (5). The support film (20) has an installation surface on which the board (1) is installed and a non-installation surface opposite to the installation surface. The opening (5) in the support (2) penetrates the support (2) from the installation surface to the non-installation surface of the support film (20). The board (1) has an upper end fixed to the installation surface of the support film (20) and a lower end extending through the opening (5) and placed on the non-installation surface of the support film (20).

Abstract: An LED board includes a flexible printed circuit and multiple LED-mounted parts arrayed on the circuit board at regular intervals in a constant direction. The LED-mounted parts each include multiple LEDs. The circuit board includes LED portions including the LED-mounted parts and non-LED portions including no LED-mounted parts that are arrayed alternately. The LED-mounted parts each have, in an array direction in which the LED-mounted parts are arrayed, a dimension equal to an interval between adjacent LED-mounted parts of the arrayed LED-mounted parts. A surface emitter includes multiple LED boards fitted together, with LED-mounted parts on each LED board overlapping non-LED portions of an adjacent LED board of the LED boards. The LED board and the surface emitter with the above structures easily upsize a video display device.

Abstract: A display unit includes light emitting elements, a circuit board having a mount surface on which the light emitting elements are mounted and a waterproof film covering the light emitting elements and the mount surface. The mount surface includes a first region and a first recess. In the first region, the light emitting elements are mounted and the waterproof film is adhered. The waterproof film includes a first cover portion covering the first recess and having a surface area that is greater than an area of a first projection coverage obtained by perpendicular projection of the first recess onto an imaginary plane parallel to the first region.

Abstract: A display device includes a substrate, light-emitting elements that emit visible light, and a protective film that is waterproof, has transmissivity to visible light, and has weather resistance. The light-emitting elements are arrayed in a regular manner and separated from each other on one surface of the substrate. The protective film covers each of the light-emitting elements and closely adheres to the one surface of the substrate between the light-emitting elements. Each of the light-emitting elements includes light emitting diodes covered with a resin having a weather resistivity that is lower than a weather resistivity of the protective film.

Abstract: A light emitting device includes an LED chip to emit light, and a light emitting element holding member that includes a base on which the LED chip is disposed and a wall standing from the base such that the wall has an inner surface that faces the LED chip. The wall includes inner surfaces that are formed in black, and inner surfaces that are formed in white. The inner surfaces that are formed in black mutually oppose each other. The inner surfaces that are formed in white mutually oppose each other in a direction orthogonal to the direction in which the inner surfaces that are formed in black mutually oppose each other.

Abstract: The display unit includes a circuit board, a plurality of light emitting elements mounted on a mounting surface of the circuit board, a case on which the circuit board is placed, and a waterproof film covering the mounting surface of the circuit board, the plurality of light emitting elements and the case. The waterproof film and the case seal the mounting surface of the circuit board and the plurality of light emitting elements.

Abstract: A light-emitting element includes a casing that includes a recess, an LED chip disposed on a bottom surface of the recess of the casing, a sealing member to close the recess and permit passage of light emitted by the LED chip. The sealing member includes an interface with a space external to the casing, the interface includes an inclined portion at least at a peripheral edge portion of the sealing member, and the inclined portion gradually approaches a bottom surface of the recess as the inclined portion gets farther away from an optical axis of the LED chip.

Abstract: For organic EL panels with a hollow-sealed structure to meet the demand of flat or large displays, the inconvenience of contact of drying anent etc touching the organic EL elements in the sealed space is avoided. An organic EL panel includes a panel substrate, a light-emitting part with a plurality of organic EL elements having an anode, an organic layer and a cathode laminated on the panel substrate, and a sealing substrate configured to be bonded onto the panel substrate through an adhesive layer to seal the light-emitting part. The sealing substrate includes a supporting projection projecting toward the panel substrate. A supporting margin facing to the bottom face of the supporting projection is provided where the organic EL elements is not formed within a region of the light-emitting part on the panel substrate.
