    摘要: A light emitting element with a high contrast is realized. A light emitting device with a high contrast is achieved by using the light emitting element with an excellent contrast. The light emitting element has a layer containing a light emitting substance interposed between a first electrode and a second electrode, and the layer containing the light emitting substance includes a light emitting layer, a layer containing a first organic compound, and a layer containing a second organic compound. The first electrode has a light-transmitting property, and the layer containing the first organic compound and the layer containing the second organic compound are interposed between the second electrode and the light emitting layer. Furthermore, color of the first organic compound and color of the second organic compound are complementary.

    摘要: A novel benzoxazole derivative having high excitation energy, particularly high triplet excitation energy is provided. A light-emitting element having high current efficiency is provided by application of the novel benzoxazole derivative for the light-emitting element. A light-emitting device, an electronic device, and a lighting device each having reduced power consumption are provided. The benzoxazole derivative is represented by General Formula (G1). In the formula, R11 to R14 and R21 to R27 separately represent any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, and Z represents either a sulfur atom or an oxygen atom.
