Lighting device and display device

A lighting device comprising:

• a light source;
• a guide plate having a rectangular plate shape having outer peripheral edge surfaces and plate surfaces, the outer peripheral edge surfaces including a pair of edge surfaces that are opposite from each other and one of the pair of edge surfaces being a light entrance surface through which light emitted by the light source enters and one of the plate surfaces being a light exit surface through which the light exits and another one of the plate surfaces being an opposite plate surface;
• a reflecting member arranged opposite the opposite plate surface of the light guide plate and reflecting the light;
• an exit light reflection portion disposed on a side of the light exit surface of the light guide plate and reflecting light travelling within the light guide plate to accelerate exiting of the light through the light exit surface, the exit light reflection portion including unit reflecting portions extending in a second direction that is parallel to the pair of edge surfaces of the outer peripheral edge surfaces of the light guide plate including the light entrance surface, the unit reflecting portions being arranged at intervals in a first direction that is parallel to another pair of edge surfaces of the outer peripheral edge surfaces of the light guide plate not including the light entrance surface;
• an opposite plate surface-side anisotropic light collecting portion included on a side of the opposite plate surface of the light guide plate, the plate surface-side anisotropic light collecting portion including opposite plate surface-side cylindrical lenses that extend in the first direction and are arranged in the second direction, the opposite plate surface-side anisotropic light collecting portion having a relatively low occupied ratio with respect to the second direction in a portion near the light entrance surface in the first direction and having a relatively high occupied ratio in a portion far away from the light entrance surface;
• and
• flat portions included on a side of the opposite plate surface of the light guide plate and being flat in the first direction and the second direction and having a relatively high occupied ratio to the opposite plate surface with respect to the second direction in a portion near the light entrance surface in the first direction and having a relatively low occupied ratio in a portion far away from the light entrance surface.
