Lighting device and display device

A lighting device comprising:

• at least one light source;
• a light guide plate including a section of a peripheral surface opposed to the at least one light source defined as at least one light entering surface, a section of the peripheral surface opposite from the at least one light entering surface defined as at least one opposite surface, and a plate surface defined as a light exiting plate surface through which light exits;
• an optical sheet disposed over the light exiting plate surface and configured to exert optical effects on the light exiting from the light guide plate through the light exiting plate surface;
• and
• at least one light blocking member in an outer edge area of at least one of the light guide plate and the optical sheet to block the light from the light guide plate through the light exiting plate surface, the at least one light blocking member extending in a peripheral direction along the peripheral surface in which the at least one light entering surface and the at least one opposite surface are arranged.
