Liquid crystal display panel and liquid crystal display device

A liquid crystal display panel comprising, sequentially from a viewer side:

• A first linearly polarizing plate;
• a first λ/4-wavelength layer;
• a first substrate including a color filter, a black matrix, and a second f/4-wavelength layer;
• a dielectric layer;
• an alignment film;
• a liquid crystal layer;
• a second substrate;
• and a second linearly polarizing plate;
• the liquid crystal display panel further comprising a sealing material disposed so as to surround the liquid crystal layer in a plan view,
• wherein the second A/4-wavelength layer is a stack of an alignment layer and a liquid crystalline polymer,
• the second λ/4-wavelength layer is disposed closer to the liquid crystal layer than the color filter and the black matrix are and such that a side surface of the second A/4-wavelength layer lies inside an arrangement region of the sealing material,
• the dielectric layer covers a surface of the second λ/4-wavelength layer on the liquid crystal layer side and the side surface of the second A/4-wavelength layer,
• the sealing material is disposed on the dielectric layer, and
• the first λ/4-wavelength layer and the second A74-wavelength layer are disposed such that their slow axes are perpendicular to each other.
