Problems solved by technology

[0013] However, since it is difficult to completely pour some of the liquid crystals when the orientation is controlled by electrode slits or protrusions, there is a problem of lowered transmittance.
Moreover, the more complex the orientation control structure, the larger the area occupied by the slits or protrusions, the greater the impact
In addition, when electrode slits are formed on an array substrate with a multi-thickness structure, it is difficult to process the slits, which may cause disconnection, etc.

Abstract

Provided is a transflective liquid crystal display in which bright display with high contrast and a wide viewing angle can be obtained. The liquid crystal display has a liquid crystal layer which comprises a liquid crystal having negative dielectric anisotropy and showing perpendicular alignment as an initial alignment state and which is held between a pair of substrates, and the display has a plurality of dots arranged in the image display region, with each dot region having a transmissive display region T for transmissive display and a reflective display region R for reflective display. The transmissive display regions T or the reflective regions R in two adjacent dot regions P1, P2 are arranged on the end sides of the respective dot regions so that the liquid crystal is obliquely aligned in the opposite directions to each other by an oblique electric field generated in each end side when a voltage is applied.

Description

technical field [0001] The present invention relates to a liquid crystal display device and electronic equipment, and particularly relates to a technique for obtaining a display with high luminance, high contrast, and wide viewing angle in a transflective liquid crystal display device that performs display in both reflective mode and transmissive mode. Background technique [0002] As a liquid crystal display device, a liquid crystal display device has been proposed that uses external light in a bright place like a reflective liquid crystal display device, and makes the display recognizable in a dark place by an internal light source such as a backlight. That is to say, the liquid crystal display device has both reflective and transmissive display methods, and switches to either of the reflective mode and the transmissive mode by corresponding to the brightness of the surrounding environment, so that the power consumption is reduced while even in the surrounding Clear displa...
