Abstract

A backlight and a liquid crystal display. The backlight includes: a circuit substrate, a plurality of LED chips and a first silica gel layer. The plurality of LED chips are fixed by means of die bond on the circuit substrate, and the first silica gel layer is applied to the circuit substrate and wraps the plurality of LED chips. The first silica gel layer makes light emitted by the LED chips more diffuse, thus enhancing light emission uniformity of the backlight and reducing a thickness of a backlight module.
