    • PROBLEM TO BE SOLVED: To provide a combination type polarizing plate which can be formed in a large area and, further when applied for a liquid crystal display device, can contribute improvement of a viewing angle. SOLUTION: The combination type polarizing plate 10 includes: a transparent film 31; a first polarizing plate 1 and a second polarizing plate 2 arranged side by side on one surface of the transparent film 31, wherein the first polarizing plate 1 and the second polarizing plate 2 are arranged such that the edge surface 1a of the first polarizing plate 1 and at least one edge surface 2a of edge surfaces of the second polarizing plate 2 face each other, and are stacked on one surface of the transparent film 31, and the transparent film 31 is such a film that an index ellipsoid satisfies a relation: nz>nx≥ny.
