1. A liquid crystal panel comprising, sequentially from a back surface side toward a viewing surface side:
a first substrate including a first electrode;
a first alignment film;
a liquid crystal layer containing liquid crystal molecules having a positive anisotropy of dielectric constant;
a second alignment film; and
a second substrate including a second electrode, wherein:
the liquid crystal molecules are homogeneously aligned with no voltage applied between the first electrode and the second electrode,
a polar anchoring energy 2EA and an azimuthal anchoring energy 2EB of the second alignment film are smaller than a polar anchoring energy 1EA and an azimuthal anchoring energy 1EB of the first alignment film, respectively,
the polar anchoring energy 2EA of the second alignment film is not greater than the azimuthal anchoring energy 2EB of the second alignment film, and
each of the polar anchoring energy 2EA and the azimuthal anchoring energy 2EB of the second alignment film is not greater than 1×10−4 J/m2.
