Display panel including barrier wall and liquid crystal display device having the same

A display device comprising:

• a lower substrate including a display area at which an image is displayed and a non-display area at which the image is not displayed;
• an upper substrate facing the lower substrate;
• a sealing portion at the non-display area and between the lower substrate and the upper substrate;
• an optical transmittance layer between the lower substrate and the upper substrate, the optical transmittance layer being surrounded by the sealing portion;
• a first light blocking portion on the display area of the lower substrate;
• and
• a second light blocking portion on the non-display area of the lower substrate,
• wherein
• the second light blocking portion comprises:
• a base portion,
• a barrier wall protruding toward the upper substrate from the base portion, and
• a protruding portion protruding toward the upper substrate from the barrier wall, and
• a total height of the second light blocking portion at the base portion thereof is less than a total height of the second light blocking portion at the barrier wall and the protruding portion thereof.
