PROCESS FOR PRODUCING ORGANIC ELECTROLUMINESCENT ELEMENT, AND ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE

摘要

The present invention provides a process for producing an organic EL element and an organic EL display device, the process rendering a reduction in film formation time possible while inhibiting the width of a blurred portion from increasing. This process for producing an organic EL element employs a scanning vapor deposition method. In the process, a plurality of ejection orifices is provided to each vapor deposition source so that the ejection orifices respectively face the openings of a restriction plate, the multiple ejection orifices which face each opening being spaced from each other so that the sum of distributions represented by expression (1) is 1 or less. [Numeral formula 1] cos(ni+3)&thetas;i×ri/Ri (1) Ri represents the maximum film formation rate of an ejection orifice i of the multiple ejection orifices that face each opening; i represents an integer of 1 to m; m represents the number of the multiple ejection orifices that face the opening; ri represents the actual film formation rate of the ejection orifice i in a vapor deposition step; ni is the value of n (0 or a larger number) of the ejection orifice i; and &thetas;i represents the angle between the main film-formation direction and the line segment which connects the ejection orifice i and any point within the film formation region.
