Embodiment 1）

[0027] figure 1 is a diagram illustrating the configuration of the planar light source device in Embodiment 1. Such as figure 1 As shown in , the planar light source device includes a linear light source device 1 , a light guide plate 2 and a frame 3 . Here, the linear light source device 1 is arranged such that the linear light source device 1 has its light emitting direction toward the light guide plate 2 , and the linear light source device 1 is in contact with the side surface of the light guide plate 2 . The frame 3 has a structure in which the light guide plate 2 and the linear light source device 1 are inserted so that the position of the linear light source device 1 is fixed relative to the light guide plate 2 .

[0028] The configuration of the linear light source device 1 will be explained in more detail below. figure 2 is a sectional view illustrating the configuration of the linear light source device 1 . image 3 is a diagram illustrating the linear light sou...

Abstract

A linear light source device comprises a wiring substrate in a rectangular shape and having 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, and a sealing resin that seals the light emitting elements, wherein the linear light source device is to be arranged on a side surface of a light guiding plate to form a planar light source device, and an external connection terminal is arranged on a surface of the wiring substrate that is opposite to a surface of the wiring substrate where the light emitting element are arranged and in a central portion in the longitudinal direction of the wiring substrate, and connected with the wiring pattern.

Description

technical field [0001] The present invention relates to a light source device having a plurality of light emitting elements arranged in a linear configuration and arranged on a side surface of a light guide plate for making a planar light source device. Background technique [0002] There is a planar light source device having a light guide plate and a linear light source device arranged on a side surface of the light guide plate (for example, see Patent Reference 1) as a liquid crystal display panel for use in a cellular phone or a digital camera or the like. [0003] The linear light source device includes: a printed circuit board having an elongated rectangular-shaped wiring pattern formed thereon; and connected to the wiring pattern of the printed circuit board; reflectors, which are respectively arranged on one side and the other side in the length direction of each light emitting element, and have inclined surfaces; and encapsulation resin, which is used to encapsulate...
