Abstract:
The liquid crystal display panel sequentially includes: a first polarizing plate; a first substrate; a first alignment film; a liquid crystal layer containing liquid crystal molecules; a second alignment film; a second substrate; and a second polarizing plate. The liquid crystal display panel is a normally black liquid crystal display panel capable of shifting into a transparent display state. The first alignment film and the second alignment film have been subjected to alignment treatment such that a first domain and a second domain in which alignment vectors are different from each other are arranged side by side in a column direction. In a plan view, a liquid crystal alignment axis of the first domain and a liquid crystal alignment axis of the second domain obliquely intersect a polarization axis of the first polarizing plate and a polarization axis of the second polarizing plate and are parallel to each other.
