A stilbene derivative, which is a novel substance exhibiting excellent color purity as blue, and a light emitting device, a display device, and an electronic device using the novel substance are provided. The stilbene derivative of the novel substance is represented by the following general formula (1). In this general formula (1), Ar < 1> and Ar < 2> represent a C6-C25 aryl group, and this aryl group may have a C1-C4 alkyl group. Ar 1 and Ar 2 may be bonded directly to each other to form a five-membered ring. In addition, A < 11> represents either of the substituents represented by the following general formula (1-1)-general formula (1-3). In addition, the bonding position of nitrogen which has Ar < 1> and Ar < 2> couple | bonded with stilbene, and A < 11> may be any of an ortho position, a meta position, and a para position with respect to the double bond of stilbene, respectively. |
