发明名称 Método para produzir dispositivo de display de cristal líquido, e dispositivo de display de cristal líquido
摘要 <p>The present invention provides a method for easily producing at low cost a liquid crystal display device which can achieve a higher contrast ratio in a wide viewing angle range, and a liquid crystal display device. The present invention relates to a method for producing a liquid crystal display device including a first polarizer, a first birefringent layer, a liquid crystal cell, a second birefringent layer, and a second polarizer in this order. The production method comprises at least one of the following first and second steps. The first step includes: laterally stretching a raw film for the first birefringent layer including a material with positive intrinsic birefringence to produce the first birefringent layer; and bonding the first polarizer and the first birefringent layer by roll-to-roll processing. The second step includes: laterally stretching a raw film for the second birefringent layer including a material with negative intrinsic birefringence to produce the second birefringent layer; and bonding the second polarizer and the second birefringent layer by roll-to-roll processing.</p>
