Penetration of moisture and propagation of cracks is prevented in a polarizer. An adhesive is provided to cover one or more edges of the polarizer to seal the side section of the polarizer. The adhesive fills initial cracks to prevent the initial crack from being propagated to the inside of the polarizer. A protective film and the adhesive include a material having a hydrophobic characteristic. In a method of fabricating a polarizer, a polarizing film is shaped to form a polarizing layer, and a protective film is then attached by applying an adhesive onto the edges of the polarizing layer. Then, the adhesive is cured, and the protective film having the polarizing layer attached is processed, thereby dividing the protective film into a plurality of polarizers. The adhesive can firmly fix the crack since the adhesive is fills in cracks in the polarizing layer.

A color conversion panel according to an exemplary embodiment of the present invention includes: a substrate; a first color filter and a second color filter adjacent to the first color filter disposed on the substrate; a first color conversion layer disposed on the first color filter; and a second color conversion layer disposed on the second color filter, wherein each of the first color conversion layer and the second color conversion layer includes at least two quantum dots representing different colors, and wherein the first color filter displays a different color from the second color filter.

Optical stacks are described. In particular, optical stacks including reflecting-absorbing polarizers and quarter-wave plates are disclosed. The optical core of the optical stack—which includes a reflecting-absorbing polarizer with at least one skin layer including polarizing dye—may be co-extruded or co-stretched.

A film stack comprises an oriented first layer comprising polyvinyl alcohol disposed on an oriented second layer comprising naphthalene dicarboxylate containing copolyester resin. The oriented second layer has in-plane birefringence Δnxy<0.02.

An integrated touch module and a touch display device are provided. The integrated touch module has a touch sensing structure formed on a polymer film. The polymer film, a liquid crystal phase retardation layer, and a linear polarizing layer constitute a circular polarizing element. The average reflectance of the circular polarizing element in the visible light range is less than 5%, and the standard deviation of the reflectance is less than 0.2%. The touch display device includes the integrated touch module.

Provided is a viewing angle control polarizing plate that has asymmetric transmission characteristics, does not cause moire even in a case of being used in combination with a high-definition image display device, and is capable of easily following a curved surface and a viewing angle control system with high productivity. The viewing angle control system includes at least a first polarizer and an optically anisotropic layer, in which an absorption axis of the first polarizer forms an angle of 45° or greater with respect to an in-plane direction, and a main axis of a refractive index of the optically anisotropic layer is tilted in the in-plane direction.

A polarizing plate includes a polarizing layer over a base material, an inorganic insulation layer over the polarizing layer, and a water-resistant layer over the inorganic insulation layer, where the water-resistant layer covers sidewalls of the polarizing layer and sidewalls of the inorganic insulation layer, when the base material is viewed from a top plan view.

A waveguide illuminator includes an input waveguide, a waveguide splitter coupled to the input waveguide, and a waveguide array coupled to the waveguide splitter. The waveguide array includes an array of out-couplers out-coupling portions of the split light beam to form an array of out-coupled beam portions for illuminating a display panel. To reduce optical interference, the waveguide illuminator may have two interlaced waveguide arrays energized by two different light sources. Output polarizations of neighboring light pixels of a display illuminated with such waveguide illuminator may be orthogonal to each other. The frames to be displayed may be broken down into sequentially displayed sub-frames with interleaved pixels.
