摘要： A display apparatus includes a display panel, a light source and a plurality of a light guiding plate. The LGP includes light incident, counter, light emitting and rear surfaces. The counter and rear surfaces are respectively opposite to the light incident and light emitting surfaces. The light emitting surface includes an ineffective light emitting area making contact with the light incident surface and an effective light emitting area connecting the ineffective light emitting area with the counter surface. The counter surface of a first light guiding plate is disposed overlapping the light incident surface of a second light guiding plate along a first direction, so that the rear surface partially overlaps with the effective light emitting area of the second light guiding plate, and the light guiding plates collectively form a light guiding plate array along the first direction.
