    "abstract": "We study the angular structure of polarization of light transmitted through a\nnematic liquid crystal (NLC) cell by theoretically analyzing the polarization\nstate as a function of the incidence angles. For a uniformly aligned NLC cell,\nthe $4\\times 4$ matrix formalism and the orthogonality relations are used to\nderive the analytical expressions for the transmission and reflection matrices.\nThe polarization resolved angular patterns in the two-dimensional projection\nplane are characterized in terms of the polarization singularities: C points\n(points of circular polarization) and L lines (lines of linear polarization).\nIn the case of linearly polarized plane waves incident on the homeotropically\naligned cell, we present the results of detailed theoretical analysis\ndescribing the structure of the polarization singularities. We apply the theory\nto compute the polarization patterns for various orientational structures in\nthe NLC cell and discuss the effects induced by the director orientation and\nbiaxiality.",
