Display device and method for manufacturing the same

A display device comprising:

• a display panel including a first pixel region, a second pixel region, and a third pixel region each emitting source light;
• and
• a light conversion panel disposed to be spaced apart from the display panel in a thickness direction of the display panel,
• wherein the light conversion panel includes:
• a base layer;
• a barrier rib disposed on a lower surface of the base layer and having first openings corresponding to the first pixel region, the second pixel region, and the third pixel region;
• a first light conversion pattern disposed in a first-first opening among the first openings corresponding to the first pixel region and converting the source light into first color light;
• a second light conversion pattern disposed in a first-second opening among the first openings corresponding to the second pixel region and converting the source light into second color light;
• a transmission pattern disposed in a first-third opening among the first openings corresponding to the third pixel region and transmitting the source light;
• and
• a division pattern disposed between the display panel and the barrier rib, and the transmission pattern and the division pattern include a same material.

A method for manufacturing a display device, the method comprising:

• preparing a substrate on which a first pixel region and a second pixel region are defined;
• forming a barrier rib including first openings corresponding to each of the first pixel region and the second pixel region;
• forming a photoresist layer on the substrate and the barrier rib;
• patterning the photoresist layer to form a division pattern having division openings overlapping each of the first pixel region and the second pixel region in a plan view;
• and
• forming a light conversion pattern inside ones of the first openings corresponding to the first pixel region and the second pixel region.
