Light source device and display apparatus

摘要

Provided are a light source device which includes a light guide plate configured to emit light made incident thereon through one surface thereof, a reflection sheet which has one surface facing the other surface of the light guide plate and is configured to reflect the light made incident on the light guide plate to one surface side of the light guide plate, and an opposite member oppositely disposed to the other surface of the reflection sheet, such that an occurrence of wrinkles and deflection in the reflection sheet may be prevented with a simple configuration, while surely fixing the position of the reflection sheet, and a display apparatus including the light source device.;The reflection sheet includes a first reflection sheet piece and a second reflection sheet piece, wherein the first reflection sheet piece is pinched by the light guide plate and the back cover, and the second reflection sheet piece is held by the first reflection sheet piece.

主权项

1. A light source device which includes a light guide plate configured to emit light made incident thereon through a first surface thereof, a reflection sheet which has a first surface facing a second surface of the light guide plate being opposite to the first surface of the light guide plate and is configured to reflect the light made incident on the light guide plate to the first surface side of the light guide plate, and an opposite member oppositely disposed to a second surface of the reflection sheet being opposite to the first surface of the reflection sheet, wherein the light source device comprises:
an optical sheet oppositely disposed to the first surface of the light guide plate; and a sheet holding part configured to push a peripheral edge part of the optical sheet to the opposite member, wherein the reflection sheet comprises: a first reflection sheet piece pinched by the light guide plate and the opposite member at a position matching with the sheet holding part in a thickness direction of the light guide plate; and a second reflection sheet piece sandwiched between the first reflection sheet piece and the light guide plate at a position mismatching with the sheet holding part in the thickness direction of the light guide plate.
