Provided is an image display device including an image display cell and a polarizing plate placed on a viewer side of the image display cell. The first polarizing plate includes a polarizer and a first protective film. The first protective film is placed on a viewer-side principal surface of the polarizer and satisfies following relations: (i) 0 nm≦Re1≦3000 nm; (ii) Nz1≧7; and (iii) Rth1>2500 nm. Re1, Rth1 and Nz1 are defined by following equations: Re1=(nx1−ny1)d1; Rth1=(nx1−nz1)d1; and Nz1=Rth1/Re1, wherein d1 represents a thickness of the first protective film, nx1 represents a refractive index in a direction of an in-plane slow axis of the protective film, ny1 represents a refractive index in a direction of an in-plane fast axis of the protective film, and nz1 represents a refractive index in a direction of the thickness of the protective film.
摘要:
An adhesive composition which allows for preventing misalignment when mutually laminating adherends, mutually strongly bonding the adherends when correction of lamination is not required, as well as peeling the adherends without causing any damage thereto when correction of lamination is required. The adhesive composition includes an adhesive base agent consisting of a monomer and a polymerization initiator. Adhesive strength of the adhesive composition changes to take a local maximum value, a local minimum value and a value greater than the local maximum value along with increase of irradiation amount of the electromagnetic wave or particle beam irradiated to the adhesive composition under a predetermined temperature environment.

Provided are an optical display device manufacturing system and a method for manufacturing an optical display device which can bond optical films to both surfaces of a liquid crystal cell in good condition with a simpler constitution. A first optical film F11 is fed in an orthogonal direction with respect to the width direction from a first material roll R1 formed by winding the first optical film F11 in such a manner that an absorption axis B1 extends in the orthogonal direction, and then the first optical film F11 is cut and bonded to one surface of a liquid crystal cell. A second optical film F21 is fed in an orthogonal direction with respect to the width direction from a second material roll R2 formed by winding the second optical film F21 in such a manner that an absorption axis B2 extends in the width direction, and then the second optical film F21 is cut and bonded to the other surface of the liquid crystal cell. Accordingly, it is possible to bond the first optical film F11 and the second optical film F21 in the crossed nicols relation, without the provision of the mechanism for rotating the liquid crystal cell W or the like.
