Title: CIRCULARLY POLARIZING PLATE, ORGANIC EL IMAGE DISPLAY DEVICE, AND MANUFACTURING METHOD FOR CIRCULARLY POLARIZING PLATE
Abstract:
The present invention provides: a circularly polarizing plate comprising a phase difference layer, a polarization separation layer and a polarization layer in this order, the polarization separation layer including a polarization separation region that reflects linearly polarized light in one polarization direction in a visible light wavelength range and transmits linearly polarized light in a polarization direction orthogonal to the polarization direction, and a non-reflective region; an organic EL image display device comprising the circularly polarizing plate and a light-emitting element substrate having an organic electroluminescence layer group; and a manufacturing method for the circularly polarizing plate comprising forming the polarization separation region configured from a wire grid polarizer by conductor deposition via a light-blocking mask. The organic EL image display device of the present invention has high luminance, and low screen reflectance when the light is off.
