摘要： A backlight source comprises a back plate (1), a light source (2) and at least two light guiding plates (3), wherein the at least two light guiding plates are spaced from each other and disposed in the same layer over the back plate (1), the light source (2) is disposed in a spacing region (4) formed between two adjacent light guiding plates (3), and a light emitting surface (21) of the light source (2) is opposite to a first side of the light guiding plate (3) facing the spacing region (4). The backlight source enables the luminance of a whole big-size light guiding plate to be more uniform and the luminance of the optically distant end of the plate to reach a level required for display. Moreover, with respect to a direct illustrating type of backlight source, the backlight source is lighter and thinner, and has lower power consumption. The present disclosure further provides a display device.
