Liquid crystal display device

Abstract

The present invention relates to a liquid crystal display device, and provides a liquid crystal display device with good visibility. In a liquid crystal display device in which the liquid crystal layer is twisted and aligned in the state where no electric field is applied, the Δnd value of the liquid crystal layer at 550 nm is 300 nm to 400 nm, and the polarization axis directions of a pair of linear polarizers are respectively relative to the end faces on the near side of the liquid crystal layer. The alignment direction of the liquid crystal molecules is approximately parallel or approximately vertical, and the angle formed by the polarization axes of a pair of linear polarizers is designed to be greater than 85° and less than 90°. In a liquid crystal display device in which the liquid crystal layer is aligned substantially vertically in a state where no electric field is applied, the angle formed by the polarization axes of the pair of linear polarizers is 85° or more and less than 90°. In a liquid crystal display device driven by a transverse electric field, the uniaxial orientation angle of the liquid crystal layer in a state where no electric field is applied is greater than -45° and less than -40°, or greater than +40° and less than 45° (here, " "Angle" means that when viewed from the front with respect to the display screen, the 3 o'clock direction of the clockwise direction is set to 0°, the counterclockwise direction from there is set to "+", and the clockwise direction is set to "-").

Description

[0001] This application is a divisional application of: [0002] Invention name: liquid crystal display device [0003] Application date: September 9, 2011 [0004] Application number: 201110267243.8. technical field [0005] This application claims priority based on Japanese Patent Application Japanese Patent Application No. 2010-207821 for which it applied on September 16, 2010, and uses all the indication content. [0006] The present invention relates to a liquid crystal display device. Background technique [0007] Liquid crystal displays take advantage of advantages such as low power consumption, small size and light weight, and are used as monitors for personal computers (PCs) and portable information terminals, etc., and display devices for TVs, etc. A liquid crystal display device includes a plurality of pixels arranged in a matrix, and performs light modulation for each pixel to display an image. [0008] As a liquid crystal display device, an active matrix liq...

Problems solved by technology

[0039] However, when a liquid crystal mode of a lateral electric field drive method capable of obtaining a good CR in a wide range of viewing angles is applied to a multi-screen liquid crystal display device, a field of view in which display characteristics are deteriorated is likely to occur due to crosstalk of a plurality of displayed images.
