Light source module and display device

A display device, comprising:

• a circuit board;
• and
• a plurality of light source modules disposed on the circuit board, wherein each of the light source devices comprises:
• a quantum dot cell, comprising:
• a first glass substrate;
• a second glass substrate disposed corresponding and in parallel to the first glass substrate, the second glass substrate having a light-emitting surface at a side of the second glass substrate opposite to the first glass substrate;
• a quantum dot region disposed between the first glass substrate and the second glass substrate, wherein a quantum dot material is disposed in the quantum dot region;
• and
• a reflective sealant disposed between the first glass substrate and the second glass substrate and surrounding the quantum dot region, wherein a reflectivity of the reflective sealant ranges from 30% to 100%;
• a light emitting element disposed at a side of the first glass substrate opposite to the quantum dot region, wherein the light emitting element emits a light with a first wavelength range, the light enters the quantum dot region, and the quantum dot material converts the light with the first wavelength range into a light with a second wavelength range;
• and
• an adhesive layer disposed at an outer side of the light emitting element for attaching the light emitting element to a surface of the first glass substrate, wherein the adhesive layer is disposed between the light emitting element and the first glass substrate in a direction parallel to a thickness direction of the first glass substrate.
