Abstract: A polarizing film includes a polarizing layer and a twisted liquid crystal layer. The twisted liquid crystal layer includes liquid crystal molecules arranged to have different degrees of inclination from each other with respect to a transmission axis of the polarizing layer in a thickness direction. A top tilting angle is about 64° to about 75°; a bottom tilting angle is about 135° to about 145°, and the twisted liquid crystal layer has a thickness of about 2.5 μm to about 3 μm in the thickness direction.

Abstract: A polarization film includes: a polarization layer; a first light compensation film arranged on one side of the polarization layer and including a positive A plate; and a second light compensation film arranged on one side of the first light compensation film and including a positive C plate. A value of ne(+C)−ne(+A) is positive at a wavelength of 450 nm and negative at a wavelength of 650 nm. Here, ne(+A) denotes an extraordinary refractive index of the first light compensation film and ne(+C) denotes an extraordinary refractive index of the second light compensation film.

Abstract: A display device including: a display panel including first and second display areas, the first display area including first pixels, the second display area including second pixels and a transmission area; a memory storing correction values of a pixel value; a controller generating corrected data by correcting image data using the correction values of the pixel value; and a data driver outputting a data signal corresponding to the corrected data to the display panel, wherein one of the correction values of the pixel value includes a pixel function value for illuminance of external light regarding one of the first pixels and the second pixels, the pixel function value makes a white color coordinate of the first display area equal to a white color coordinate of the second display area based on an external light characteristic, an external light reflection characteristic, and an emission characteristic.
