Claims33
A method for producing an electric field effect light-emitting device comprising the steps of:
- forming a first conductive film on a supporting body;
- forming a light-emitting layer comprising a diamond-like carbon film including an oxygen atom at a concentration not greater than 5 atomic percent on said first conductive film;
- and
- forming a second conductive film on said light-emitting layer.
