Embodiment Construction

[0023] Now, the present invention will be described more specifically with reference to the accompanying drawings. figure 1 An LCD device according to an embodiment of the present invention is shown. An LCD device, generally indicated by reference numeral 100 , includes a backlight unit 120 , an LC panel 121 , and a control circuit 122 . The LC panel 121 includes a light-incident-side polarizing film 101, a transistor array (TFT) substrate 102, an alignment film 111, an LC layer 103, an alignment film 113, a color filter (CF) substrate 104, and a light-emitting-side polarizing film 105 in the form of This order is along the direction of light transmission.

[0024] The LC layer 103 includes uniformly aligned LC molecules 112 therein. Each of the polarizing films 101 , 105 has a function of passing therethrough light having a polarization coincident with the polarization axis of the polarizing films 101 , 105 . The polarizing films 101, 105 are arranged such that their tran...

Abstract

An LCD device includes an LC panel and a backlight unit having a backlight and a luminous intensity control unit. The backlight has a peak luminous intensity in each of the wavelength ranges corresponding to red, green and blue. The luminous intensity control unit controls the peak luminous intensity of the wavelength range corresponding to blue of the lower gray scale of the LCD unit to be lower than the peak luminous intensity of the higher gray scale, thereby preventing chromaticity on the screen from shifting. Blue offset.

Description

technical field [0001] The present invention relates to a liquid crystal display device (LCD) having a homogeneously aligned LC layer. Background technique [0002] In general, an LCD device includes a liquid crystal (LC) panel in which an LC layer including LC molecules is sandwiched between a pair of substrates and a pair of polarizing films sandwiching the LC panel. An LCD device presents images on its screen by controlling the tilt angle of the long axis of the LC molecules. For example, an in-plane switching mode (IPS mode) LCD device includes a uniformly aligned LC layer and a pair of polarizing films arranged such that their polarization axes are perpendicular to each other. To display an image, an electric field parallel to the substrate surface is applied to the LC layer to rotate the LC molecules parallel to the substrate surface. [0003] It is known that in an LCD device, a gray scale represented on a screen of the LCD device includes a color change from an ini...
