Claim 2:
3. The light-emitting touch panel according to claim 1, wherein each of the light-emitting elements has a light-emitting angle, a projection height of the light-emitting element is defined as Equation (I), the cover plate has a thickness in the first direction, a height difference between the second height and the first height is greater than a difference between the projection height and the thickness, the height difference between the second height and the first height is less than the projection height, and the second width of the bright region in the second direction is greater than the first width, wherein
Equation (I) is, Hc
