According to one embodiment, a lighting device includes a light source, and a semi-transmissive reflection layer opposing the light source. The semi-transmissive reflection layer includes a pattern including transmitting portions or reflecting portions. The pattern includes a pattern formed of the transmitting portions each having a hole conformation in a region to which a high volume of light form the light source incident, and a pattern formed of the reflection portions each having a dot conformation in a region to which a low volume of light form the light source incident.

According to one embodiment, an lighting apparatus includes a base member, a light source configured to emit visible light, and a translucent cover including a translucent region which covers at least a front surface of the light source and emits the light emitted from the light source to the outside. The light source is provided on a front surface flat section of the base member, a luminous intensity of the light emitted from the light source has a directionality which is strong in a normal direction of the front surface flat section and becomes zero on a rear surface side. The translucent cover includes a domed shape having a maximum diameter at a position higher than a height of the position where the light source is arranged, and a transmittance of a region opposing the light source is 60% or less.

An envelope of an image display device has a rear substrate and a front substrate opposed to the rear substrate. A plurality of pixel display elements are provided inside the envelope. The front substrate and the rear substrate have respective peripheral portions thereof sealed together with a sealing material. At least one of the front substrate and the rear substrate has a seal surface reformed and sealed with the sealing material.
摘要:
An envelope of an image display device has a front substrate and a rear substrate opposed to the front substrate, and respective peripheral edge portions of the front substrate and the rear substrate are sealed together with a sealing layer which contains an electrically conductive sealing material. An electrode for energizing the sealing layer is attached to the envelope. The electrode is formed of an electrically conductive member, is in electrical contact with the sealing layer, and has a conduction portion exposed to the outside.
摘要:
A vacuum envelope of an image display apparatus has a rear substrate and a front substrate, which are opposed to each other, and a plurality of electron emitting elements are located in the vacuum envelope. The respective peripheral portions of the front substrate and the rear substrate are sealed together with a sealing layer between them. A diffusion layer that contains a component of the sealing layer is formed on the substrate side of an interface between the sealing layer and the front substrate and/or the rear substrate.
摘要:
An image display apparatus includes an envelope which has a front substrate and a rear substrate opposed to each other and individually having peripheral edge portions sealed together. A sealed portion is sealed by a sealing member. the sealing member has electrical conductivity and melts when supplied with current. After the sealing member in the sealed portion is supplied with current and melted during manufacture, the current supply is stopped to cool and solidify the sealing member, whereupon the respective peripheral edge portions of the front substrate and the rear substrate are selected together.
摘要:
A vacuum envelope of a flat display device comprises a front substrate and a rear substrate opposed to each other and a rectangular frame body provided between respective peripheral portions of the front substrate and the rear substrate. The frame body has projections that protrude outward from individual corner portions. In manufacture, the projections are nipped and pulled outward, and the frame body is positioned with respect to the substrates and joined thereto with a longitudinal tension applied to each side of the frame body.
