Light Emitting Device and Method for Manufacturing Thereof

A light-emitting device comprising:

• a conductive substrate;
• a first insulating layer over the conductive substrate;
• a first electrode over the first insulating layer;
• a first opening in the first electrode and the first insulating layer, a part of the conductive substrate being exposed in the first opening;
• a second insulating layer covering a side of the first opening and a part of the first electrode;
• a light-emitting layer over the first electrode and the second insulating layer, the light-emitting layer being electrically connected to the first electrode;
• a second opening in the light-emitting layer and the second insulating layer, a part of the conductive substrate being exposed in the second opening;
• and
• a second electrode over the light-emitting layer and in the second opening, the second electrode being electrically connected to the conductive substrate.

A method for manufacturing a light-emitting device comprising the steps of:

• forming a conductive layer over a substrate;
• forming a first insulating layer over the conductive layer;
• forming a first electrode over the first insulating layer;
• forming a first opening in the first electrode and the first insulating layer thereby exposing a part of the conductive layer;
• forming a second insulating layer including a second opening, the second insulating layer covering a side surface and a part of the first electrode, and a part of the conductive layer being exposed in the second opening;
• forming a light-emitting layer over the second insulating layer, the first electrode, and the part of the conductive layer exposed in the second opening;
• and
• forming a second electrode over the light-emitting layer and the second insulating layer, the second electrode being electrically connected to the conductive layer.
