摘要:
The present invention provides a vapor deposition apparatus, a vapor deposition method, and a method for producing an organic electroluminescent element which can control the vapor deposition rate on the substrate in the entire vapor deposition region with excellent precision. The vapor deposition apparatus of the present invention that forms a film on a substrate includes a first thickness monitor; and a vapor deposition unit including a vapor deposition source, the apparatus being configured to perform vapor deposition while controlling the distance between a portion of the vapor deposition source designed to eject a vaporized material and a surface of the substrate on which the vapor deposition is performed, based on a measurement result from the first thickness monitor.

The present invention provides a method for producing an organic EL element capable of shortening the film formation time while suppressing an increase in the blur width; and an organic EL display device. The method is for producing an organic EL element by scanning vapor deposition, in which one or more vapor deposition sources each are provided with ejection orifices that face the respective openings of a limiting plate, and the ejection orifices facing the same opening are spaced from each other to give a sum of distributions represented by the following formula (1) of 1 or smaller, cos(ni+3)θi×ri/Ri (1) wherein Ri represents a maximum film-formation rate of an ejection orifice i among the ejection orifices facing the same opening, i represents an integer of 1 or greater and m or smaller, m represents the number of the ejection orifices facing the same opening, ri represents the actual film-formation rate of the ejection orifice i in the vapor deposition step, ni is an n value, which is zero or more, of the ejection orifice i, and θi represents an angle formed by a main film formation direction and a segment connecting the ejection orifice i and a point within the film formation region.

摘要:
On a vapor deposition target surface of a vapor deposition target substrate placed on a substrate tray in a vapor deposition device, display regions on which vapor deposition particles are to be deposited are arranged in alignment to be apart from each other in a direction parallel with a scanning direction, and the substrate tray includes a blocking part configured to block the vapor deposition particles to be deposited onto regions adjacent to the display regions in a direction parallel with the scanning direction. This prevents a degree of freedom in designing of the vapor deposition target substrate from being restricted even in performing scan vapor deposition.
