摘要： In a chassis 13, a cold cathode tube 15 is housed, a planar optical member 16 is provided in an opening portion, and a support component 20 that can support the optical member 16 is mounted. The support component 20 includes a linear support portion 24 linearly extending in parallel with a plane direction of the optical member 16. The linear support portion 24 is curved to become progressively lower from end sides toward a middle side of the optical member 16. The optical member 16 can be warped and deformed by a gap ensured between the optical member 16 and the linear support portion 24. When the optical member 16 is warped and deformed, the linear support portion 24 supports the optical member 16 in a height position corresponding to the warped shape.
