Waterproof light emitting module and display device

A waterproof light emitting module, comprising:

• a circuit board;
• a light emitting diode on the circuit board, the light emitting diode having a light emitting surface, a first non-light emitting surface and a second non-light emitting surface;
• a light guide plate adjacent to the light emitting surface of the light emitting diode;
• and
• a waterproof layer covering the first non-light emitting surface and the second non-light emitting surface of the light emitting diode, wherein the waterproof layer comprises a single-sided adhesive tape, a double-sided adhesive tape and a substrate, and the substrate is fixed on the circuit board through the double-sided adhesive tape, and the substrate covers the first non-light emitting surface of the light emitting diode, and the single-sided adhesive tape is in contact with the substrate and covers the second non-light emitting surface of the light emitting diode.
