Display device containing multiple dams made of organic insulating layers

A display device, comprising:

• a display part including a plurality of pixels arranged on a substrate;
• a plurality of dams in a first peripheral part adjacent to the display part, the plurality of dams being extended in a first direction of the first peripheral part and arranged in a second direction crossing the first direction, each of the plurality of dams including at least one selected from a first organic insulating layer and a second organic insulating layer;
• and
• a blocking part disposed between the plurality of dams and corresponding to a removed portion of the first and second organic insulating layers, wherein:
• at least one power voltage line which transmits a power supply voltage applied to the plurality of pixels is disposed in the first peripheral part,
• the at least one power voltage line includes a first source metal pattern and a second source metal pattern connected to the first source metal pattern through a contact hole formed in the first organic insulating layer, and
• the second organic insulating layer is on the second source metal pattern.
