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.
