    • A liquid crystal layer, made of a liquid crystal material having a negative dielectric anisotropy, is sealed between an opposing substrate and a pixel substrate that are arranged face to face with each other; thus, a liquid crystal panel of the birefringence control type is constructed. In this liquid crystal panel, the liquid crystal molecules, provided as the liquid crystal material, are kept in an oriented state in which they incline by an angle in the range of 3° to 10° with respect to the direction that is normal to the opposing substrate and the pixel substrate. Upon application of a driving voltage to the liquid crystal layer, since the pretilt angle, which is the initial angle of inclination of the liquid crystal molecules, is set at a value greater than that of a conventional apparatus, the occurrence of reverse tilt regions can be suppressed. Thus, the disclination line, which is formed by the effect of electric potentials exerted between the adjacent pixels, is shifted toward the edge of the pixel. The shift of the disclination line suppresses the occurrence of disclination in a wider region, thereby increasing the effective reflectance of the pixels.
    • 由具有负介电各向异性的液晶材料制成的液晶层被密封在彼此面对面配置的相对基板和像素基板之间; 因此,构成了双折射控制型的液晶面板。 在该液晶面板中,设置为液晶材料的液晶分子被保持在取向状态,在该取向状态下,它们相对于垂直于液晶的方向倾斜3°至10°的范围 相对的基板和像素基板。 在向液晶层施加驱动电压时,由于作为液晶分子的初始倾斜角度的预倾角被设定为大于常规装置的值,所以反向倾斜区域的出现可以 被压制 因此,通过施加在相邻像素之间的电位的作用形成的旋错线朝向像素的边缘移动。 旋错线的偏移抑制了较宽区域中的旋错的发生,从而增加了像素的有效反射率。
