Display apparatus

A display apparatus, comprising:

• a substrate including a display region and a non-display region;
• a thin film transistor disposed on the substrate;
• at least one light-emitting device electrically connected to the thin film transistor;
• a power supply line disposed on the substrate and configured to supply driving power to the at least one light-emitting device;
• and
• a pad unit disposed on the substrate in the non-display region,
• wherein the first power supply line comprises a first fan-out wire portion connected to the pad unit, and a first extension portion connected to the first fan-out wire portion,
• the second power supply line comprises a second fan-out wire portion connected to the pad unit, and a second extension portion connected to the second fan-out wire portion, and
• wherein the first extension portion has a width W1 and the second extension portion has a width W2, and wherein the width W1 is greater than the width W2.

A display apparatus, comprising:

• a substrate;
• and
• a display unit disposed on the substrate, the display unit comprising a display region and a non-display region disposed around the display region,
• wherein the display unit comprises:
• a first light-emitting device disposed in the display region;
• a first power supply line and a second power supply line configured to supply driving power to the first light-emitting device;
• and
• a pad unit disposed in the non-display region,
• wherein the first power supply line comprises, in the non-display region, a pair of first fan-out wire portions electrically connected to the pad unit, a pair of first extension portions, each electrically connected to each of the pair of first fan-out wire portions, respectively, and a first body portion connected to each of the pair of first extension portions, and
• the second power supply line comprises, in the non-display region, a pair of second fan-out wire portions electrically connected to the pad unit, a pair of second extension portions, each electrically connected to each of the pair of second fan-out wire portions, respectively, and a second body portion connected each of the pair of second extension portions,
• wherein each of the pair of second extension portions is disposed on opposite sides of the pair of the first extension portions, and
• wherein one of the pair of first extension portion has a width W1 and one of the pair of second extension portion has a width W2, and wherein the width W1 is greater than the width W2.
