1. A display device comprising:
a first pixel comprising a first organic EL element and a first color conversion layer provided over the first organic EL element; and
a second pixel comprising a second organic EL element and a second color conversion layer provided over the second organic EL element,
wherein an area of the first pixel is larger than an area of the second pixel,
wherein the first organic EL element and the second organic EL element comprise the same light-emitting material,
wherein an emission spectrum of light emitted from the first pixel and an emission spectrum of light emitted from the second pixel are different from each other,
wherein the first organic EL element is electrically connected to one of a source and a drain of a first transistor,
wherein the other of the source and the drain of the first transistor is electrically connected to a power supply line,
wherein a gate of the first transistor is electrically connected to one electrode of a first capacitor and one of a source and a drain of a second transistor,
wherein the second organic EL element is electrically connected to one of a source and a drain of a third transistor,
wherein the other of the source and the drain of the third transistor is electrically connected to the power supply line,
wherein a gate of the third transistor is electrically connected to one electrode of a second capacitor and one of a source and a drain of a fourth transistor, and
wherein each of the first transistor, the second transistor, the third transistor, and the fourth transistor comprises indium.
