Optical member unit, lighting device for display, display, and television receiver

摘要

An optical member 15 is constituted by sticking a lens sheet 28 capable of transmitting light irradiated toward a liquid crystal panel 11 and a diffuser sheet 27 together. The lens sheet 28 is provided with a lens portion 30 having a large number of unit lenses 29 aligned on the front surface, while on the rear surface, provided with a reflecting layer 32 having an opening 31 corresponding to the lens portion 30. The optical member 15 is received on the backside by receiving members 21 and 24 provided respectively in a holder 17 and a lamp holder 16, while being held from the front by a frame 18. An inclined posture supporting member 33 is provided in the receiving member 24 in the holder 17, which supports the optical member 15 in a posture so that the edge 15a of the optical member 15 and the arrangement of the unit lenses 29 are inclined relatively to the arrangement of the pixel electrodes PE in the liquid crystal panel 11, by abutting an outer circumferential end surface 15b in the optical member 15.
