Abstract
A liquid crystal display device has been disclosed. The liquid crystal display device provides a display with a high reflectance (high transmittance) and a high color purity while maintaining white balance and adjusts the white balance by changing the occupied area instead of the transmission characteristics of a CF in order to prevent yellowing of the display due to a low-temperature light source.
Claims10
A liquid crystal display device comprising:
- two substrates arranged so as to be opposed to each other;
- parallel flat electrodes formed on the surfaces of the two substrates and at least one of which is a transparent electrode;
- and a liquid crystal layer having liquid crystal sandwiched between the parallel flat electrodes and in which the liquid crystal molecules are aligned so that the direction of the major axis of the liquid crystal molecule becomes substantially perpendicular to at least one of the electrode surfaces while no voltage is being applied between the parallel flat electrodes, that is, during the period with no voltage being applied, wherein an alignment process is carried out on at least one of the parallel flat electrodes so that while a voltage is being applied between the parallel flat electrodes, that is, during the period with a voltage being applied, the liquid crystal molecules are tilted almost in the same direction and a domain, in which the tilting orientation of the liquid crystal molecules in the oblique electric field on the outer surface of a pixel and the alignment orientation meet at an angle exceeding 90°, is minimized.
