Display panel and method of manufacturing the same

A display panel comprising:

• an upper display substrate comprising a plurality of pixel areas and a light blocking area disposed adjacent to the pixel areas;
• and
• a lower display substrate comprising a plurality of light emitting devices respectively overlapping the pixel areas, the upper display substrate comprising:
• a base substrate;
• a color filter layer disposed on the base substrate;
• a light control layer disposed on the color filter layer and comprising a transmission part comprising transmission portions respectively overlapping first pixel areas arranged in one pixel column and first light blocking portions overlapping the light blocking area and disposed between the transmission portions and a first conversion part comprising first conversion portions respectively overlapping pixel areas arranged in another pixel column and second light blocking portions overlapping the light blocking area and disposed between the first conversion portions;
• and
• is a barrier layer overlapping the light blocking area and comprising first barriers disposed between the first conversion part and the transmission part and disposed on the color filter layer and first sub-barriers disposed on the second light blocking portions of the first conversion part, wherein at least a portion of each of the first barriers protrudes from the light control layer to face the lower display substrate, and a height of the first barriers is substantially equal to a height of the sub-barriers.

A method of manufacturing a display panel, comprising the steps of:

• disposing a color filter layer on a base substrate in which a plurality of pixel areas and a light blocking area adjacent to the pixel areas are formed;
• substantially simultaneously forming sub-barriers overlapping a first light blocking area of the light blocking area, which is disposed between the pixel areas arranged in one pixel column, and transmission portions overlapping the pixel areas arranged in another pixel column and transmitting a first color light exiting from a lower display substrate on the color filter layer;
• forming a first conversion portion converting the first color light exiting from the lower display substrate to a second color light and overlapping the pixel areas arranged in the one pixel column;
• determining a height from a lower surface of the first conversion portion that does not overlap with the sub-barriers to a lower surface of the first conversion portion that overlaps with the sub-barriers;
• and
• forming barriers overlapping a second light blocking area of the light blocking area, which is disposed between the transmission portion and the first conversion portion, on the color filter layer to a height based on the determined height.
