On the TFT substrate (10), a vapor deposition layer is formed by use of a vapor deposition device (50) which includes (i) a vapor deposition source (85) having injection holes (86) and (ii) a vapor deposition mask (81) having openings (82) through which vapor deposition particles injected from the injection holes (86) are deposited so as to form the vapor deposition layer. The TFT substrate (10) has a plurality of pixels two-dimensionally arranged in a pixel region (AG), and terminals of a plurality of wires (14), which are electrically connected with the plurality of pixels, are gathered outside a vapor deposition layer formation region.
