  • Publication number: 20110026271
    Abstract: Disclosed is an optical member for use in liquid crystal displays, which can correct the light path and can minimize the loss of light, so that light in a wider angular range can be collected forwards. Even when a distance between the optical member and a light source is shortened, the optical member can exhibit good hiding performance and prevent deformation caused by heat. Upon expansion and shrinkage, the optical member is not scratched and does not generate noise at a portion in contact with a support pin.
