wherein a gap is interposed between the light emitter mounting portion and the connector mounting portion and between the arm portion and the connector mounting portion.
2. The display device circuit board according to claim 1 ,
wherein, in the flexible substrate, the arm portion includes two arm portions, and
wherein the two arm portions are positioned on either side of the connector mounting portion in a second direction that intersects with the first direction.
3. The display device circuit board according to claim 1 ,
wherein the flexible substrate further includes a pixel circuit connection portion that protrudes from the base portion in a direction opposite to the first direction.
4. The display device circuit board according to claim 1 ,
wherein the flexible substrate further includes a support portion located at a side opposite to the base portion in the first direction.
5. The display device circuit board according to claim 1 further comprising
a light emitter reinforcing plate provided on one main surface of the light emitter mounting portion.
6. The display device circuit board according to claim 1 ,
wherein the connector reinforcing plate has a cutout formed at an outer edge thereof.
7. The display device circuit board according to claim 1 ,
wherein the connector mounting portion has an opening or a cutout.
8. The display device circuit board according to claim 1 further comprising
a connector provided on the other main surface of the connector mounting portion.
