Light emitting device and electrode substrate

A light emitting device, comprising:

• a first insulating layer disposed on the substrate;
• at least one transistor:
• a first electrode pattern and a second electrode pattern disposed on a first surface of the first insulating layer;
• at least one LED chip including a first terminal and a second terminal, and the first terminal electrically connected to the first electrode pattern and the second terminal electrically connected to the second electrode pattern;
• and
• a reflective pattern disposed on a second surface side of the first insulating layer opposite to the first surface;
• wherein
• the first electrode pattern and the second electrode pattern are electrically separated by a first gap,
• the reflective pattern includes a linear pattern overlapping with the first gap, and
• the at least one transistor is disposed between the substrate and the reflective pattern, and overlapped with the reflective pattern.
