Problems solved by technology

However, when a stretched film is used in the production of a polarizing plate and a wavelength plate as in the prior art, there is a limit to reducing the film thickness of the stretched film itself, and a sufficiently thin sheet cannot be obtained.

Abstract

A method for manufacturing an organic EL display, comprising an optical member forming step of applying an optical film coating liquid containing liquid crystal molecules and a solvent on a substrate on which an organic light emitting diode has been preformed and drying the optical member, To form an optical film with liquid crystal molecules aligned.

Description

technical field [0001] The invention relates to a method for manufacturing an organic EL display. Background technique [0002] For example, in a display using an organic light emitting diode (OLED: Organic Light Emitting Diode) (hereinafter also referred to as an "organic EL (Electro Luminescence) display"), a circular polarizing plate is used to suppress external light reflection. The circular polarizing plate is produced by laminating a linear polarizing plate and a wavelength plate (retardation plate) so that their polarization axes cross at 45 degrees. [0003] Also, for example, the wavelength plate may be formed only so that its polarization axis is inclined by 15 degrees or 75 degrees. Therefore, it is necessary to form polarizing plates and wavelength plates at arbitrary angles. In addition, in order to make the polarization axes of the polarizing plate and the wavelength plate intersect at an arbitrary angle, it is necessary to form the polarizing plate and the w...
