An electronic device includes a casing having a display part () provided with an image display panel (), a operation part () provided with operation keys (), and a joint part () that connects together the display part and the operation part, and a lightguide plate () disposed in the casing. The lightguide plate is an edge-light type lightguide plate having a display illuminating part () illuminating the image display panel, a key illuminating part () illuminating the operation keys, and a connecting part () that connects together the display illuminating part and the key illuminating part and that guides light therebetween. The lightguide plate is deformable in accordance with the deformation of the casing.

Lightguide plate and electronic device

A light-emitting device used in a linear array of a plurality of them includes a semiconductor light-emitting element, a substrate on which the semiconductor light-emitting element is mounted, and a light-transmitting sealing resin formed on the front surface of the substrate to seal the semiconductor light-emitting element. Of each of the peripheral edge surfaces of the substrate and the sealing resin, at least one side surface that faces in the direction of the array is inclined in the array direction.

Light-emitting device, linear light source, planar light unit and display apparatus

Light-emitting diode

An elongated transparent light leading member is provided above a light source, leading member is provided opposite to the light source and a hole is formed in the light leading member at a position above the light source. The hole has an inverted triangular shape, opposite sides of the hole are provided for reflecting light beams emitted from the light source in a longitudinal direction of the light leading member.

Linear light source unit

A transparent planar light leading plate is provided adjacent to a light source, and a hole is formed in the light leading plate at a position opposite to the light source. The hole has an inverted triangular shape, opposite sides of the hole are provided for reflecting light beams emitted from the light source.
