摘要： A first phase plate and a third phase plate, which constitute a polarizer structure, cooperate to impart a phase difference of a ¼ wavelength to linearly polarized light that emerges from a first polarizer plate. A second phase plate and a fourth phase plate cooperate to impart a phase difference of a ¼ wavelength to linearly polarized light that emerges from a second polarizer plate. Slow axes in planes of the first phase plate and the second phase plate are substantially parallel.

摘要： Transmission display regions are disposed at both sides of a reflection display region of a pixel electrode in a pixel of an array substrate. An insulating layer having a first insulating layer and a second insulating layer that face the transmission display regions and the reflection display region in the pixel electrode is formed on the counter electrode of the counter substrate. Second insulating layers exist at both sides of the first insulating layer. The motion of liquid crystal molecules is symmetrical with respect to the reflection display region. Liquid crystal orientation stability can be enhanced at a plurality of pixels. A defect such as unevenness in display due to orientation fluctuation of the liquid crystal molecules in the liquid crystal layer can be avoided. A liquid crystal cell having a high display quality level is provided.

摘要： Transmissive display regions are disposed at both sides of a reflective region in each pixel so as to sandwich the reflective region therebetween. A first height adjusting layer is formed below a counter electrode of a counter substrate, whereby the thickness of a liquid crystal layer in the reflective display region is made smaller than the thickness of the transmissive display regions. The motion of liquid crystal molecules at the peripheral edge of the reflective display region and the motion of liquid crystal molecules at the peripheral edge of the transmissive display region are symmetrical at both sides of the reflective display region. The alignment stability of the liquid crystal in the pixel can be enhanced. Defects such as unevenness of display caused by fluctuation of alignment of the liquid crystal molecules in the liquid crystal layer can be avoided. The asymmetrical property of the field-of-view angle can be avoided.
