Optical laminate, polarizing plate, method of producing polarizing plate, image display, manufacturing method of image display, and method of improving visibility of image display
The present invention relates to a method for improving the visibility of an image display apparatus capable of obtaining an image display apparatus having excellent antireflection performance and spot contrast even when an optical laminate having a light-transmitting base material having a birefringence in a plane such as a polyester film is used . To this end, the present invention is a method for improving the visibility of an image display apparatus having an optical laminate having an optically functional layer on one side of a light-transmissive base material having a birefringence in a plane, wherein the light- The optical laminate is disposed such that the axis and the vertical direction of the display screen of the image display device are parallel to each other.
