Title:
Luminescent device
Document Type and Number:
Japanese Patent JP5982506
Kind Code:
B2
Abstract:
In a light emitting device using a light emitting element, the invention provides a sealing structure capable of preventing ingress of moisture from the outside and obtaining adequate reliability. The light emitting device has a light emitting element comprising a light emitting layer formed between a first electrode and a second electrode and a pixel portion comprising the light emitting element. The entire surface of the pixel portion is covered with the second electrode. An impermeable insulating film is formed in contact with the first electrode of the light emitting element. The edge of the first electrode and the impermeable insulating film are covered with a partition wall. An opening is formed along the circumference of the pixel portion in the partition wall. The opening passes through the partition wall in the thickness direction, and the side wall and the bottom face thereof are covered with the second electrode.
