Abstract:
An organic electroluminescence display panel includes a thin-film transistor layer above a substrate. A planarizing film is above the thin-film transistor layer with contact holes being formed in the planarizing film. A bank is above the planarizing film. The bank includes openings arranged in rows and columns that define regions for forming organic electroluminescence elements. Each opening is between a pair of adjacent concaves in one of the columns. The concaves are formed in an upper surface of the bank and sunken into the contact holes. The upper surface of the bank has repellency. A light-emitting layer is formed in each opening by ejecting drops of an ink from nozzles of an inkjet head into the openings while moving the inkjet head relative to the substrate. The nozzles further eject drops of the ink into the concaves when above the concaves for ejecting the drops of the ink through every nozzle.
