1. A polarizing plate, comprising:
a polarizer; and a resin layer directly in contact with the polarizer, wherein the resin layer is a layer obtained by polymerizing and curing a boronic acid monomer having a boronic acid group denoted by Formula (1) and a polymerizable group, and a multifunctional monomer, Re(550) and Rth(550) of the resin layer respectively satisfy Expression (X) and Expression (Y) described below,
Re(550)≦10 nm Expression (X)|Rth(550)|≦10 nm Expression (Y) a thickness of the polarizer is less than or equal to 35 μm, Re(550) indicates in-plane retardation (nm) at a wavelength of 550 nm, and Rth(550) indicates retardation (nm) in a thickness direction at a wavelength of 550 nm, and in Formula (1), R1 and R2 each independently represent a hydrogen atom, a substituted or unsubstituted aliphatic hydrocarbon group, an aryl group, or a heterocyclic group, R1 and R2 may be connected to each other to form a ring, and * indicates a bonding position. |
