Abstract: The present disclosure provides a backlight source, including: a light-guide plate, a diffuser arranged at a light-exiting side of the light-guide plate, and a light bar arranged at a light-entering side of the light-guide plate and including a light-emitting diode (LED) lamp and a flexible circuit board connected to the LED lamp. The flexible circuit board includes a base material, and a first solder mask and a second solder mask arranged at two surfaces of the base material opposite to each other. The base material includes a first region where the second solder mask is arranged and a second region where the second solder mask is not arranged. The second region is located at a side of the base material adjacent to the light-guide plate. The diffuser includes, at an end adjacent to the light bar, a connection member partially or completely covering the second region.

Abstract: A light guide plate (LGP) and a display device are disclosed. The LGP comprises at least one mesh point; each mesh point is provided with a plurality of microstructures; and all the microstructures on each mesh point are arranged on the same curved surface. The LGP can solve the problem that incident light is subjected to total reflection in the LGP so that the luminous uniformity of the LGP can be improved.
