Problems solved by technology

[0011] However, in the liquid crystal display device of Patent Document 1, since it is necessary to switch the driving voltage to supply two pixel areas in one pixel, the driving control of the liquid crystal display device is complicated, and a circuit for realizing such driving control is produced. The problem that the structure also becomes complicated

Embodiment Construction

[0060] An example of the present invention will now be described as follows. In addition, in this embodiment, as a liquid crystal display mode, a liquid crystal display device employing a CPA (continuous pin wheel alignment) mode will be described.

[0061] The liquid crystal display device 1 among the present embodiment is shown in Fig. 1 (a) and Fig. 1 (b), is formed and is arranged on the face that controls this display face 2a on the face opposite to the display face 2a of liquid crystal display panel 2. The configuration of the viewing angle characteristic control panel (light transmission state setting device, light transmission state setting unit, light transmission state switching unit) 3 for viewing angle characteristics.

[0062] The viewing angle characteristic control panel 3 has a function of switching the state of light diffusion and light transmission, thereby switching the viewing angle characteristics on the display surface 2 a of the display panel 2 .

Abstract

The liquid crystal display device is equipped with a liquid crystal display panel 2 whose liquid crystal alignment state is so controlled that when front transmissivity in white display and transmissivity at an oblique field angle are each 1, the transmission intensity at the oblique field angle is larger than the transmission intensity of the front and there is a 1st region where a white tinged phenomenon occurs at the oblique field angle and a 2nd area where no white tinged phenomenon occurs at the oblique field angle in one or a plurality of pixel regions constituting a pixel. Further, provided is a panel 3 for field angle characteristic control which sets the whole or part of the 2nd region of the liquid crystal display panel 2 in a light shield state or light transmission state for oblique view at need, so the liquid crystal display panel can be switched between narrower field angle characteristics and wider field angle characteristics with simple constitution.

Description

technical field [0001] The present invention relates to a liquid crystal display device capable of switching between a wide viewing angle characteristic and a narrow viewing angle characteristic, and an electronic device equipped with the liquid crystal display device. Background technique [0002] In general, an active matrix liquid crystal display device has a structure in which two glass substrates are fixed facing each other, and liquid crystals are sealed in the gap between them. A transparent common electrode is formed on one glass substrate, and multiple electrodes are formed on the other glass substrate. Each transparent pixel electrode is formed in a row and column, and a circuit for independently applying a voltage to each pixel electrode is formed. [0003] A liquid crystal display device is characterized by a narrow viewing angle characteristic because the above-mentioned structure is sandwiched between polarizing plates to display. [0004] In order to broaden ...
