Light source member, display device including the same, and manufacturing method for the same

A display device comprising:

• a light source member;
• and
• a display panel facing the light source member,
• wherein the light source member comprises:
• a circuit board;
• a reflection plate facing the circuit board, the reflection plate comprising in order from the circuit board:
• a base layer having a cross-sectional shape defining a plurality of grooves of the reflection plate, each of the plurality of grooves recessed in a direction towards the circuit board, and
• a light control pattern layer on the base layer and in the plurality of grooves which are defined by the base layer, which wavelength-converts, absorbs or reflects light, the light control pattern layer having a shape corresponding to the cross-sectional shape of the base layer;
• and
• a plurality of light emitting elements in the plurality of grooves which include the light control pattern layer on the base layer.

A method of manufacturing a light source member, the method comprising:

• providing a plurality of light emitting elements on a circuit board;
• providing a reflection plate comprising in order from the circuit board:
• a base layer having a cross-sectional shape defining both a plurality of grooves, and a plurality of through-holes which respectively correspond to the plurality of grooves, and
• a light control pattern layer on the base layer and in the plurality of grooves which are defined by the base layer, which wavelength-converts, absorbs or reflects light, the light control pattern layer having a shape corresponding to the cross-sectional shape of the base layer,
• wherein the plurality of light emitting elements are in the plurality of grooves which include the light control pattern layer on the base layer;
• and
• providing the circuit board having the plurality of light emitting elements thereon combined with the reflection plate having the plurality of grooves, the plurality of through-holes and the light control pattern layer, to respectively extend the plurality of light emitting elements into the plurality of through-holes to provide the light source member,
• wherein the providing of the reflection plate comprises:
• providing the plurality of grooves and the plurality of through-holes in the base layer;
• providing a light control pattern material on the base layer, at positions corresponding to the plurality of grooves;
• and
• providing the light control pattern layer from the light control pattern material, by curing the light control pattern material,
• wherein the providing of the plurality of grooves in the base layer and the providing of the light control pattern material on the base layer, are performed at a same time.
