Electrohydrodynamic (EHD) convection in thin cells filled by dielectric liquids is considered. First, a brief review of practical applications of the cells is presented, which includes liquid pumps, dynamic light scattering and electrochemiluminescence (ECL) displays. In the ECL devices EHD streams play the main role in ion transport, increasing current density more than 1000 times. ECL permits us to observe the shapes of EHD streams while correlation between electrical and optical kinetic characteristics gives information to the conclusion about the structure and velocities of the streams. A physical model is proposed to explain obtained dependencies and experimental results are compared with theoretical ones.
