Light source device, display apparatus, and method of manufacturing light source device

摘要

Provided are a light source device capable of uniformly illuminating, a display apparatus, and a method of manufacturing the light source device. Since a reflection sheet is adhered to a light guide plate through an adhesive layer, deflection thereof is suppressed. Since dot parts are filled in openings of an optical layer, it would be difficult for the dot parts to be distorted by an outer force. In addition, since the dot parts are formed by forming the optical layer and the adhesive layer in a large area in which an occurrence of distortion during forming is minimal, it would be difficult for the dot parts to be distorted during forming the same. Therefore, an occurrence of luminance unevenness caused by the deflection of the reflection sheet or the distortion of the dot parts may be suppressed. From the above result, it is possible to uniformly illuminate by the light source device.

主权项

1. A light source device, comprising:
a reflection sheet having light reflecting properties; a light guide plate in which the reflection sheet is disposed on a side of one surface thereof and which is configured to emit light emitted by a light source unit from a front surface thereof; an optical layer which is formed on the one surface, provided with openings, and configured to guide the light incident on the one surface to a side of the front surface, wherein the optical layer has a lower light refractive index than the light guide plate; and an adhesive layer which is formed on a rear surface of the optical layer and the one surface which is exposed from the openings, and has light scattering properties or light reflecting properties, wherein the reflection sheet is adhered to the light guide plate through the adhesive layer.
