Abstract
A first data signal line connected to one of two subpixels that emit light of the same color, a second data signal line connected to the other of the two subpixels, and a correction circuit electrically connected to the first data signal line and the second data signal line are included. When the second data signal line is at a floating potential, the correction circuit allows electrical conduction between the first data signal line and the second data signal line to correct the floating potential.
Claims16
A display device comprising:
- a first data signal line connected to one of two subpixels that emit light of a same color;
- a second data signal line connected to the other one of the two subpixels;
- a correction circuit electrically connected to the first data signal line and the second data signal line;
- a display area including the two subpixels;
- and
- a non-display area surrounding the display area, wherein:
- when the second data signal line is at a floating potential, the correction circuit allows electrical conduction between the first data signal line and the second data signal line to correct the floating potential,
- the non-display area includes a bending area that is bendable and a terminal area in which an electronic circuit chip is mounted,
- each of the first data signal line and the second data signal line extends from the display area to the terminal area via the bending area, and
- the correction circuit is included in a correction circuit area positioned between the display area and the bending area.
