POLARIZING PLATE FOR MINIMIZING THE REFLECTION OF AN EXTERNAL LIGHT AND LOWERING THE REFLECTIVITY OF A SHORT WAVELENGTH AND AN ORGANIC LIGHT EMITTING DEVICE INCLUDING THE SAME

摘要

PURPOSE: A polarizing plate and an organic light emitting device including the same are provided to improve the light loss of blue emitting spectrum.;CONSTITUTION: A phase difference film (30) is formed at one side of a polarizing film (20). A protection film (10) is laminated on the other side of the polarizing film. The protection film uses a reflection preventing film, a low refraction rate film, and a hard coating film. The polarizing film has transmissivity of 0.95 to 1.1. The phase difference film controls phase difference or has view angle improving function by controlling the optical property of lights. The phase difference film varies linearly polarized light to circularly polarized light or circularly polarized light to linearly polarized light by granting a phase difference as much as λ/4 to two polarizing elements which are mutually perpendicular and parallel to the optical axis of phase difference film as a λ/4 phase difference film.;COPYRIGHT KIPO 2013
