Abstract

The invention discloses a flexible substrate used in a luminescent device. The substrate comprises a flexible substrate and a conducting layer. The flexible substrate and the conducting layer are formed in one of the following two ways: (1) the flexible substrate is organosilicon adhesive which is solidified by ultraviolet light and the conducting layer is thin layer carbon nanotube, wherein the gap of the thin layer carbon nanotube is filled with inorganic luminescence nanometer particle; (2) the flexible substrate is organosilicon adhesive which is solidified by ultraviolet light and doped with inorganic luminescence nanometer particle, and the conducting layer is thin layer carbon nanotube, wherein the gap of the thin layer carbon nanotube is filled with organosilicon adhesive which is solidified by ultraviolet light and doped with inorganic luminescence nanometer particle. According to the substrate provided in the invention, the problems of the poor surface flatness of the thin layer carbon nanotube and the poor bonding force between the carbon nanotube and the flexible substrate are solved, and the conductivity of the conducting layer and the obstructing capability to water and oxygen of the substrate are improved.
