摘要 |
Disclosed is a method for manufacturing a liquid crystal display device with a front plate including a step of providing, on a surface on a viewing side of a liquid crystal panel having polarizing plates on both sides, a λ/4 plate having a hard coat layer and composed of mainly a thermoplastic resin, an adhesive layer, a front plate composed of glass or acrylic, and a sealing layer containing a UV-curable tacky agent, all being stacked in this order from the viewing side; and a step of curing the sealing layer by irradiating with ultraviolet radiation from a hard coat layer side. The λ/4 plate having the hard coat layer contains 0.005 to 0.5 parts by mass of a compound which shows an absorption peak (λmax) in a wavelength range of 260 nm to 400 nm per 100 parts by mass of the thermoplastic resin composing the λ/4 plate. |

1. A method for manufacturing a liquid crystal display device with a front plate, comprising:
providing, on a surface on a viewing side of a liquid crystal panel having polarizing plates on both sides thereof, a λ/4 plate having a hard coat layer and being composed of mainly a thermoplastic resin, an adhesive layer, a front plate composed of glass or acrylic, and a sealing layer comprising a UV-curable tacky agent, all being stacked in this order from the viewing side; and curing the sealing layer by irradiating with ultraviolet radiation from a hard coat layer side, wherein the λ/4 plate having the hard coat layer contains 0.005 to 0.5 parts by mass of a compound which shows an absorption peak (λmax) in a wavelength range of 260 nm to 400 nm per 100 parts by mass of the thermoplastic resin composing the λ/4 plate. |
