Definitions
- the present invention relates to an optical film having a reverse wavelength dispersion and a display device including the same.
- a phase retarder is a type of optical device that changes the polarization state of light passing through it, also called a wave plate.
- the polarization direction (the direction of the electric field vector) is the sum of two components (normal and extraordinary) parallel or perpendicular to the optical axis, and the vector sum of the two components depends on the birefringence and thickness of the phase retarder. Since it changes, the polarization direction after passing is different. In this case, a 90-degree change in the polarization direction of light is called a quarter-wave plate ( ⁇ / 4), and a 180-degree change is called a half-wave plate ( ⁇ / 2).
- the retardation value of the phase retarder depends on the wavelength, and the wavelength dispersion of the retardation value is classified into positive wavelength dispersion, flat wavelength dispersion, reverse wavelength dispersion, and the like.
- the phase retarder exhibiting reverse wavelength dispersion is most useful because it has a predetermined phase difference ( ⁇ / 4, ⁇ / 2, etc.) in a wide wavelength band, and a phase retarder formed of a conventional resin film mostly shows positive wavelength dispersion. .
- Japanese Unexamined Patent Publication No. 1998-068816 Japanese Unexamined Patent Publication No. 1998-090521, Japanese Unexamined Patent Publication No. 1999-052131, and Japanese Unexamined Patent Crab 2000- 002841 and the like disclose a phase retarder having a layered structure in which a plurality of optically anisotropic layers are laminated.
- a laminate type phase retarder having a structure in which a plurality of optically anisotropic layers are stacked requires a complicated procedure of disposing a plurality of films while controlling the optical orientation during manufacturing, resulting in low productivity and high manufacturing costs.
- Japanese Unexamined Patent Publication No. 2002-221622 by the stretching of the film
- the wavelength dispersion there is a method of wideband ⁇ / 4 wavelength plate is disclosed comprising one of a phase delay deception
- the thickness is more than 100 ⁇ ⁇ ⁇ then that is not acceptable for a liquid crystal display element which bakchunghwa demand .
- the present invention is to provide a display device including the optical film.
- R 1 is hydrogen or a methyl group
- R 2 is an aromatic hydrocarbon group or carbon number of 5 to 20 carbon atoms
- 'R 2 is an aromatic hydrocarbon group having 5 to 20 carbon atoms or a heteroaromatic hydrocarbon group having 5 to 20 carbon atoms.
- R 5 is hydrogen, a carboxyl group, or an epoxy group.
- the weight average molecular weight (Mw) of the copolymer is 10,000 to 3,000,000, or 50,000 to 2,500,000, or 100,000 to 2,000,000.
- the film containing the copolymer may be formed on the base film comprising a cellulose triacetate film, polyethylene terephthalate film, cyclo olefin polymer film, polycarbonate film, or poly-norbornene film.
- N- vinylcarbazole about 99 weight 0/0 0 parts by weight and acrylic acid of about 1 /
- jm was obtained through the same solution casting and stretching as in Example 1. As a result of retardation value measurement for the optical film, ⁇ (450 ⁇ ) 0.86, Measured as 10, it was confirmed that the conditions according to the above relation I and II.
- the copolymer (weight average molecular weight about 135,000, glass transition degree is about the same as Example 1 except using the monomer compound containing N-vinylcarbazole about 99.5 weight 0 /. And acrylic acid about 0.5 weight 0 /. 210 ° C) was obtained. Then, except that the solution was used, the optical film having a thickness of about 68
- ⁇ - vinylcarbazole (screams) 75 parts by weight 0 /.
- the acrylic acid 25 parts by weight 0/0, the copolymer in the same manner as in Example 1, except for using the monomer compound comprising a (weight average molecular weight of about 90,000 and a glass transition temperature of about 145 ° C) was obtained.
- Example 1 and except that the solution was used The same solution casting and stretching gave an optical film of about 65
