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.
