Quantum dot plate assembly and led package and module comprising the same

A light emitting device package comprising:

• a light emitting device;
• a light transmitting plate body formed above the light emitting device and including a lower light transmitting plate, a plurality of side light transmitting plates formed on an upper surface of the lower light transmitting plate, an upper light transmitting plate corresponding to the upper surface of the lower light transmitting plate and formed on upper surfaces of the plurality of side light transmitting plates, and an empty portion formed inside;
• an adhesive layer formed between the light emitting device and the light transmitting plate body;
• and
• a wavelength converting unit including a first wavelength converting layer formed integrally with the adhesive layer and a second wavelength converting layer formed in the empty portion and covering the upper surface of the lower light transmitting plate,
• wherein the second wavelength converting layer is a QD phosphor including a particle having a smaller size than the particle of the first wavelength converting layer.

A light emitting device package comprising:

• a light emitting device emitting light of a predetermined wavelength;
• a quantum dot (QD) plate assembly converting a wavelength of the light emitted from the light emitting device;
• an adhesive layer disposed between the light emitting device and the QD plate assembly to bond the light emitting device and the QD plate assembly;
• and
• a reflection member surrounding the light emitting device and the QD plate assembly,
• wherein the QD plate assembly includes a QD material converting the wavelength of the light and a light transmitting plate body for sealing the QD material.
