The present disclosure relates to a method for manufacturing a polarizing plate. The method includes a step of preparing a transfer type retarder laminate which has a carrier substrate, an alignment film and a retarder layer sequentially; and a step of laminating the transfer type retarder laminate on one side of a polymeric stretched film containing a dichroic substance, where a peel force at a peeling angle of 90° between the carrier substrate and the retarder layer in the transfer type retarder laminate and a peeling rate of 300 mm/min is in a range of 0.10 N/20 mm to 0.13 N/20 mm. The polarizing plate can be used as a circularly polarizing plate or an optical compensation polarizing plate in various display devices.

Method for manufacturing polarizing plate

The present application relates to an optical film, an optical element and an imaging device. The optical film of the present application does not only exhibit broadband polarization conversion characteristics in the visible light region, but also has absorption bands in the visible light region. Such an optical film can be applied to an imaging device such as an augmented reality apparatus as an optical element such as a diffractive light guide plate laminate to suppress crosstalk.

Optical film, optical element, and imaging device

A method for manufacturing an optical device and an optical device is provided. The manufacturing method is capable of minimizing or eliminating dotting unevenness that may occur when an optical device is manufactured by a dotting process. In particular, even when a large cell gap is present or a polymer substrate is applied as a substrate so that high-temperature heat treatment is impossible, such method of the present application can provide an alignment film having improved orientation by improving the dotting unevenness.

Method for manufacturing optical device by varying rubbing strength

The present application relates to a light guide plate unit including a reflection plate, an adhesive layer which is provided on the reflection plate and includes a bead, and a light guide plate provided on the adhesive layer, a backlight unit including the light guide plate unit, and a liquid crystal display device including the backlight unit.

Light guide plate unit, backlight unit comprising same, and liquid crystal display device

Provided are an optical filter and a stereoscopic display device. The exemplary optical filter may be applied to the stereoscopic display device to observe a stereoscopic image in a wide viewing angle without the loss of brightness.

Optical filter

A light irradiation apparatus and a method of manufacture a photo-aligning layer are disclosed. A mask included in a light irradiation apparatus according to one embodiment is configured to irradiate the light having straightness at a high level of illumination to a subject that is apart from the mask with a certain distance. A photo-aligning layer with a desired alignment pattern can be fabricated using the mask.

Mask

A mask and an optical filter manufacturing apparatus having the same are provided. The optical filter manufacturing apparatus includes a roll used in a roll-to-roll process, a base film wound around the roll, a light source that generates light for exposure, a polarizing plate that is installed at an emission side of the light source and polarizes light generated from the light source, and a mask that causes a pattern to be formed on the base film and includes a plurality of guide slits that are opened to have a predetermined thickness and a predetermined width. According to the present invention, the entire surface of the base film can be irradiated with a uniform light quantity. Thus, a pattern can be uniformly formed on the base film, the quality of a product can be improved, and the characteristics of the base film can be accurately realized.
