Display device

A display device, comprising:

• one or more pixels placed in an active area and a pixel circuit associated with the one or more pixels;
• a power supply line placed in an inactive area outside the active area and connected to the pixel circuit;
• a first metal layer placed on the power supply line;
• an overcoating layer covering at least one side of the power supply line;
• and
• a bank on the overcoating layer and the first metal layer,
• wherein:
• the overcoating layer includes a first portion adjacent to the at least one side of the power supply line and a second portion which is farther from the power supply line than the first portion,
• the first portion of the overcoating layer has a smaller thickness than the second portion of the overcoating layer so that an upper surface of the first portion of the overcoating layer and an upper surface of the second portion of the overcoating layer form a step, both the first portion and the second portion of the overcoating layer being of a same organic material,
• the power supply line and the first metal layer are in contact with each other,
• at least one side of the first metal layer is located on the first portion, and
• the bank includes a first part in contact with the first metal layer corresponding to the first portion of the overcoating layer and a second part in contact with the second portion of the overcoating layer, the first part of the bank having a greater thickness than the second part of the bank.
