Claim Text:
1. A light-emitting device comprising: a first transistor; a second transistor; a first light-emitting element electrically connected to the first transistor, the first light-emitting element comprising: a second light-emitting element electrically connected to the second transistor, the second light-emitting element comprising: an insulator over the first transistor and the second transistor and below the layer, the insulator covering an end portion of the first electrode and an end portion of the third electrode; a first substrate over the first light-emitting element and the second light-emitting element; a first color filter on the first substrate, the first color filter overlapping the first light-emitting element; a second color filter on the first substrate, the second color filter overlapping the second light-emitting element; and a black matrix on the first substrate, the black matrix being between the first color filter and the second color filter, wherein the layer is a continuous layer at least extending from the first part to the second part, wherein the layer is in contact with a top surface of the insulator, wherein the insulator and the black matrix overlap each other, wherein a width of the insulator is larger than a width of the black matrix, wherein at least part of the black matrix is sandwiched by the first color filter and the first substrate, wherein a pixel comprises the first transistor, the first light-emitting element and a third transistor, wherein one of a source and a drain of the first transistor is directly connected to the first light-emitting element, wherein one of a source and a drain of the third transistor is directly connected to a gate of the first transistor, wherein the other of the source and the drain of the third transistor is directly connected to a signal line, wherein a channel formation region of the first transistor is made of single-crystal silicon, and wherein the first transistor is configured to operate in a saturation when the first light-emitting element emits white light.
