Abstract
A surface light source and a manufacturing method thereof and a liquid crystal display device. The surface light source includes a substrate; a plurality of light emitting diode dies arranged in an array along a row direction and a column direction on the substrate; a driving circuit on the substrate and electrically connected to the plurality of light emitting diode dies and the driving circuit being configured to control at least two of the plurality of light emitting diode dies to emit light independently of each other; and an encapsulation layer on a side of the plurality of light emitting diode dies away from the substrate. The encapsulation layer is a continuous film layer covering the plurality of light emitting diode dies.
