The lighting apparatus comprises light sources ( 16 ) and a planar light conductor ( 18 ). The planar light conductor ( 18 ) includes opposed surfaces, side surfaces and end surfaces, and a plurality of prisms ( 28 ) are provided on one of the end surfaces ( 23 ). Said a plurality of prisms ( 28 ) have the function of the linear light conductor and provides a solid planar light conductor. The configuration of said plurality of prisms ( 28 ) is varied in accordance with positions thereof. The light source ( 16 ) is arranged so that the light is incident from position near the end surface. One of the opposed surfaces has means ( 26 ) for causing the light propagating inside the planar light conductor to exit from said one of the surfaces. The side surfaces or the bottom surface of the planar light conductor has slit ( 30, 32 ) or a groove ( 34 ). The liquid crystal display includes the lighting apparatus.
