    • Provided are a reflective liquid crystal display device and a liquid crystal display unit capable of eliminating or minimizing the occurrence of misalignment specific to a vertically aligned liquid crystal due to the structure of a pixel groove and achieving higher contrast and superior image quality. In a reflective pixel electrode (42), a peripheral portion is inclined, and the reflective pixel electrode has a trapezoidal shape so that the width of the reflective pixel electrode (42) increases from the top side to the bottom side. When a side surface of the reflective pixel electrode (42) is inclined so as to eliminate verticality in a cross section of the reflective pixel electrode (42), liquid crystal molecules aligned in a horizontal direction to an extreme in a pixel groove portion can be eliminated. Even if liquid crystal molecules are locally and slightly aligned in a horizontal direction, sufficient verticality can be maintained in the pixel groove portion by an interaction with vertically aligned liquid crystal molecules around the horizontally aligned liquid crystal molecules.
    • 提供了一种反射型液晶显示装置和液晶显示装置,其能够消除或最小化由于像素槽的结构而导致的垂直排列的液晶的特定不对准的发生,并且实现更高的对比度和优异的图像质量。 在反射像素电极(42)中,周边部分倾斜,反射像素电极具有梯形形状,使得反射像素电极(42)的宽度从顶侧向底侧增加。 当反射像素电极(42)的侧表面倾斜以消除反射像素电极(42)的横截面中的垂直度时,在像素槽部分中在水平方向与极端对齐的液晶分子可以是 消除了 即使液晶分子在水平方向局部略微排列,也可以通过与水平排列的液晶分子周围的垂直取向的液晶分子的相互作用,维持像素槽部的足够的垂直度。
