The optical film has a low-refractive index layer on a plastic film, the plastic film is a biaxially stretched plastic film with an in-plane phase difference of 2500 nm or less, the low-refractive index layer is located on the outermost surface, and the optical film has a region in which ΔEab satisfies specific conditions, wherein the ΔEab is calculated from the differences between the L* value, the a* value, and the b* value obtained by measuring a laminate 1 including the optical film, the polarizer, and the surface light source under specific conditions and the L* value, the a* value, and the b* value obtained by measuring a laminate 2 including the polarizer and the surface light source under specific conditions, respectively.

Provided are an image processing device, an imaging element, an image processing method, and an image processing program that satisfactorily generate a plurality of polarized image data from polarized image data acquired from an imaging element. A processor (200B) of an image processing device (200) performs an acquisition process of acquiring first image data from an imaging element (100) in which four first-polarizers having different polarization directions are regularly provided on pixels arranged in a two-dimensional manner, a first polarized image data generation process of performing a demosaicing process on the first image data to generate four pieces of first polarized image data having different polarization directions, and a second polarized image data generation process of generating four or less pieces of second polarized image data by using the four pieces of first polarized image data and a relationship between the polarization directions of the four first-polarizers stored in the memory (200C).

A display device includes a display panel including a display area in which a plurality of pixels is disposed and a bending area bent from the display area, a polarizing layer disposed on the display panel and a light-blocking film layer disposed under the display panel, where an entirety of an upper surface of the light-blocking film layer directly contacts a lower surface of the display panel in the display area, and an area of a lower surface of the light-blocking film layer is smaller than an area of the upper surface of the light-blocking film layer.

A manufacturing process that allows for the transfer of labels formed from polarizer film to end-use products. The polarizer film is covered by a masking layer that is typically die cut to create the labels from the continuous sheet of film. Here, an additional covering layer (or layers) of a relatively stiff material is disposed over the masking layer. The addition of the covering layer results in the processed polarizer film being less susceptible to damage (related to unwanted bending) during further processing and/or shipment. Advantageously, the covering layer improves the ability to remove individual labels from the film, particularly with respect to attempting to peel off the thin masking layer.

A display device is provided. The display device comprises a first substrate, a second substrate facing the first substrate, a first polarizing layer disposed between the first substrate and the second substrate and including first line grid patterns, a light scattering layer disposed between the first polarizing layer and the second substrate, and color filter layers disposed between the light scattering layer and the second substrate.
