Abstract:
1. A method of repairing an organic electro-luminescence device with a filter, the organic electro-luminescence device including a first electrode in a side for extraction of light to outside, a second electrode placed oppositely to the first electrode, an electro-luminescence layer placed between the first electrode and the second electrode, a filter provided on a surface of the first electrode, the surface of the first electrode being opposite to another surface of the first electrode facing to the electro-luminescence layer, wherein the filter is adapted to transmit, therethrough, light in a certain-wavelength range out of the range of 400 nm to 700 nm, and a certain-wavelength absorption film placed between the filter and the electro-luminescence layer, wherein the certain-wavelength absorption film has a transmittance for light in the certain-wavelength range out of the range of 400 nm to 700 nm lower than its transmittance for light with wavelengths of 400 to 700 nm, wherein the certain-wavelength absorption film is adapted to absorb light in the certain-wavelength range to generate heat, the method comprising: detecting a portion where leak light is generated from the electro-luminescence layer as a result of application of a voltage between the first electrode and the second electrode; and directing, to the detected leak-light generating portion, laser light with a wavelength in the certain-wavelength range such that the certain-wavelength absorption film is heated by the directed laser light to repair the leak-light generating portion.
