Organic electroluminescent device and method of manufacturing the same

An organic electroluminescent device, comprising:

• a transparent substrate, comprising at least one lower electrode provided on the partial surface thereof;
• at least one insulation layer convexly provided on said transparent substrate and the partial surface of said lower electrode, crossing said lower electrode and forming a bottom as an intersection type with said lower electrode, said bottom thereof connected to a top through a neck, wherein the action width of said top is bigger than said neck, and the action width of said bottom is bigger than said top;
• and
• an organic light emitting layer provided on the surface of said lower electrode without said insulation layer sheltering, further comprising an opposite electrode provided on the surface of said organic light emitting layer.

A method of manufacturing organic electroluminescent device, comprising the steps of:

• defining and forming at least one lower electrode provided on the partial surface of a transparent substrate;
• covering an isolating layer provided on the surface of said lower electrode and said transparent substrate without said lower electrode sheltering, defining and forming at least one insulation layer, which is used to be an intersection type with said lower electrode, and a separator adjoined on said lower electrode within at least one semiconductor process and providing on an isolating layer, according to a photoresist and a short wavelength light source applied;
• and
• forming at least one organic light emitting layer and at least one opposite electrode provided on the surface of said lower electrode in order.
