Abstract:
1. A linear light source device that is to be arranged on a side surface of a light guiding plate, the liner light source device comprising: a wiring substrate in a rectangular shape and a wiring pattern formed thereon; a plurality of light emitting elements arranged on the wiring substrate in a longitudinal direction of the wiring substrate and connected with the wiring pattern on the wiring substrate; a plurality of reflectors arranged on the wiring substrate corresponding to the light emitting elements, respectively, each of which includes two parts, a first part of the two parts having a slope surface on one side which slopes downward in a first direction and a second part of the two parts having a slope surface which slopes downward in a second direction, the slope surface of the first part and the slope surface of the second part facing each other in the longitudinal direction of each light emitting element, and an upper surface of the first part which has the slope surface which slopes downward in the first direction of a first reflector of the reflectors being separated by a space from an upper surface of the second part having the slope surface which slopes downward in the second direction of a second reflector of the reflectors which is adjacent to the first part of the first reflector in the longitudinal direction; and a sealing resin sealing the light emitting elements by burying a recession portion defined by a surface of the wiring substrate where the light emitting elements are arranged and the two slope surfaces, wherein the two parts of each of reflectors have convex portions on their upper surfaces, respectively.
