Abstract: Provided is a scan vapor deposition metal mask with which a high-resolution, linear vapor deposition film pattern can be formed even on a large-sized substrate. Two first unit opening groups are included. The first unit opening groups are arranged by being shifted from each other in a Y direction so as not to be adjacent to each other in an X direction, while the first unit opening groups adjacent to each other in the Y direction are arranged by being shifted from each other in the X direction by ½ times a first opening pitch.

Abstract: An organic EL panel 10 is a bendable display panel including a plurality of pixel circuits 60 each having a light emitting element and a drive element. A data line drive circuit 15 performs, by driving data lines, an operation of writing a voltage to a control terminal of the drive element and an operation of measuring a current flowing through the drive element for the pixel circuits 60 selected by a scanning line drive circuit 14. A bending detection unit 90 detects a bending state of the organic EL panel 10 based on a measurement result of the current flowing through the drive element. A correction unit 80 corrects a video signal VS1 based on the detected bending state. With this, the bending state of a screen is detected and a change in brightness or color when the screen is bent is prevented.
