Abstract
A display device includes a first base substrate including a display area and a peripheral area around the display area; a voltage line disposed on the peripheral area of the first base substrate; a protrusion disposed on the voltage line and including a first pattern containing a first color material and a second pattern containing a second color material different from the first color material; a connection electrode disposed on the protrusion and connected with the voltage line; and a light-blocking pattern disposed on the connection electrode and provided with an opening for partially exposing the connection electrode, wherein the protrusion includes a multilayer portion where the first pattern and the second pattern overlap each other and a single-layer portion where the first pattern and the second pattern do not overlap each other, and a lateral surface of the light-blocking pattern, defining the opening, overlaps the single-layer portion.
