Method of producing light-emitting device

A method for producing a light-emitting device, comprising:

• bonding a plurality of light-emitting elements arranged in a two-dimensional array, all at once, to a plate-shaped light transmission member having an alignment mark identifying a position of a first coordinate point;
• capturing an image of the plurality of light-emitting elements bonded to the light transmission member, determining a position of a second coordinate point of the light transmission member based on positions in the image of the plurality of light-emitting elements, and calculating information about positional offset between the second coordinate point determined and the first coordinate point identified by the alignment mark of the light transmission member;
• and
• after the calculating of the information about the positional offset, forming a contact member in contact with a corresponding one of the plurality of light-emitting elements with the contact member being positioned with respect to the plurality of light-emitting elements by using the alignment mark of the light transmission member and the information about the positional offset.
