LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, ELECTRONIC DEVICE, AND LIGHTING DEVICE
First Claim
1. A light-emitting element comprising:
- a pair of electrodes; and
a light-emitting layer between the pair of electrodes, the light-emitting layer comprising a first light-emitting layer and a second light-emitting layer,wherein the light-emitting layer comprises a first region where the first light-emitting layer and the second light-emitting layer overlap with each other and a second region where the first light-emitting layer is not formed.

Abstract
The light-emitting element includes an EL layer between a pair of electrodes. The EL layer includes a light-emitting layer. The light-emitting layer includes a first light-emitting layer and a second light-emitting layer. The first light-emitting layer and the second light-emitting layer contain light-emitting substances emitting light with different colors. Any one of the first light-emitting layer and the second light-emitting layer is not formed partly so that the light-emitting layer includes a region where the any the other of the first light-emitting layer and the second light-emitting layer is only formed. A first light emitted from a region of the light-emitting layer where the first light-emitting layer and the second light-emitting layer overlap with each other is different in color from a second light emitted from a region including the non-formation region. The first light and the second light can be obtained from the light-emitting layer at the same time.

26. A light-emitting element comprising:
-
a pair of electrodes; and a light-emitting layer between the pair of electrodes, the light-emitting layer comprising a first light-emitting layer emitting phosphorescence and a second light-emitting layer emitting fluorescence, wherein the light-emitting layer comprises a first region where the first light-emitting layer and the second light-emitting layer overlap with each other and a second region where one of the first light-emitting layer and the second light-emitting layer is not formed, wherein a first light emitted from the first region is different in color from a second light emitted from the second region. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
