In our paper theoretical analyzed the decreasing of transverse-longitudinal splitting of an exciton in the GaAs/AlGaAs quantum well in the homogeneous electric field. Also the dependence of the splitting on application field is calculated. The excitonic reflectance spectra of the thick quantum well are calculated for field directed transversal to well layer. The decreasing of reflectance oscillation in the excitonic spectra because of decreasing transverse-longitudinal splitting is demonstrated.
