We theoretically and experimentally investigate the angular structure of polarization of light transmitted through planar nematic and cholesteric liquid crystal (LC) cells by analyzing the polarization state as a function of the incidence angles and the polarization characteristics of the incident wave (the ellipticity and the azimuth of polarization). The geometry of polarization-resolved conoscopic (angular) patterns emerging after the planar nematic and cholesteric LC cells is described in terms of the polarization singularities such as C-points (points of circular polarization) and L-lines (lines of linear polarization). The characteristic feature of polarization-resolved conoscopic patterns under consideration is that the conditions of C-point formation are very sensitive to polarization parameters of the incident wave.
