A light emitting device, a lighting device, a light emitting apparatus, and an electronic device are provided to improve a display quality by controlling a light emitting color. A light emitting device(106) includes a hole transport layer(105), a first layer(102), a second layer(103), a third layer(104), and a second electrode(100). The hole transport layer is formed on a first electrode(101). The third layer is formed on the hole transport layer. The second layer is formed on the third layer. The first layer is formed on the second layer. The second electrode is formed on the second layer. The first layer includes a first organic compound and a second organic compound. A weight of the second organic compound is larger than a weight of the first organic compound. The second layer includes a third organic compound and a fourth organic compound. A weight of the fourth organic compound is larger than a weight of the third organic compound. The third layer includes the first organic compound and a fifth organic compound. A weight of the fifth organic compound is larger than the weight of the first organic compound. |
