    摘要： An optical display includes an optical display element including a second substrate, a first substrate facing the second substrate, a dummy region and a metal interconnection layer thereon. A first polarizing plate on an upper surface of the optical display element has a light shielding layer therein including printed patterns separated from each other. A first printed layer includes a first point at an interface between the display and non-display regions and a second point at a vertex closest to the first point. A second printed layer includes a third point at the interface and a fourth point at a vertex closes to the third point. The light shielding layer satisfies H≤P/2, where H is a minimum value among a distance from the interface to the second point and a distance from the interface to the fourth point, and P is a width of the dummy region.

    摘要： A polarizing plate and an optical display comprising the same. The polarizing plate includes a polarizer; and a bonding layer and a first polarizer protective film sequentially stacked on a lower surface of the polarizer, wherein the first polarizer protective film includes a light shielding layer formed in at least some region on an upper surface thereof and the light shielding layer is composed of at least one printed pattern, the printed pattern being composed of a single printed layer or multiple printed layers and having a first plane formed at a top portion thereof and an inclined angle θ of greater than about 0° to about 85° or less, the inclined angle being defined between the first polarizer protective film and an imaginary line I-II connecting one distal end point I of the first plane at the top portion of the printed pattern to a point II disposed on an outer peripheral surface of the printed pattern adjoining the first polarizer protective film and closest to the distal end point I.

    摘要： A polarizing plate and an optical display including the same are provided. A polarizing plate includes a display region and a non-display region surrounding the display region and includes: a polarizer; and a bonding layer, a first polarizer protective film, and a functional coating layer sequentially stacked on a surface of the polarizer. The bonding layer includes a printed layer therein to correspond to the non-display region. The polarizing plate has a haze of about 0.1% to about 5% as measured on the functional coating layer and a reflectance difference of about 2.4% or less between the display region and the non-display region, or the polarizing plate has a haze of about 20% to about 40% as measured on the functional coating layer and a reflectance difference of about 1.5% or less between the display region and the non-display region.
