The display panel includes a plurality of pixels disposed on a substrate, a plurality of driving circuit units for driving the plurality of pixels, a first encapsulation unit for encapsulating the sensor region, and a second encapsulation unit for encapsulating the display region. The first encapsulation unit and the second encapsulation unit may be different in terms of the stacked structure of layers.

A polarizing plate and an optical display apparatus including the same are provided. A polarizing plate includes: a polarizer; and a first optically functional layer and a first protective layer sequentially stacked on a surface of the polarizer, and the optically functional layer includes a resin layer and acicular microparticles, the resin layer having a glass transition temperature (Tg) of −70° C. to −15° C. and a storage modulus of 1×10.sup.−3 MPa to 9×10.sup.−1 MPa at 25° C., and the acicular microparticles being oriented in an in-plane direction of the first optically functional layer, and, when a light absorption axis of the polarizer is 0°, orientation angles of longitudinal directions of the acicular microparticles with respect to the light absorption axis of the polarizer have an average value of −10° to +10° and a standard deviation of 15° or less.

The present invention refers to a printed three-dimensional optical component built up from layers of printing ink characterized in that the three-dimensional optical component comprises at least one foil between two consecutive layers. The present invention further relates to a corresponding manufacturing method.

An optical sheet 10 of the present invention includes a laminate including a polarizing layer 4 containing at least one kind of a light absorbing agent and having a polarizing function, and a protective layer 1 laminated on the polarizing layer 4, in which in the polarizing layer 4, a value of a* is 0 or more and 30 or less and a value of b* is 0 or more and 30 or less in an L*a*b* color system defined by JIS Z 8781-4, and in the optical sheet 10, a size of a Q Blue value defined by Australian Standard Australia/New Zealand Standard 1067-2016 is 0.70 or more. Thus, even when the optical sheet is toned to brown, blue light can be distinguished with excellent distinguishability.

A foldable display device includes a display panel, a protective base disposed on a top surface of the display panel, a polarizing plate disposed on a top surface of the protective base, a light blocking layer disposed at an edge of a top surface of the polarizing plate, and a hard coating layer for covering the polarizing plate and the light blocking layer and including a UV absorbent.

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.

There is provided a polarizer excellent in durability. A polarizer according to one embodiment of the present invention includes a resin film containing boric acid, wherein the resin film has a low-concentration portion, which contains a lower concentration of the boric acid than that in any other site, formed in an end portion thereof.
