Liquid crystal display device

A liquid crystal display device in which a plurality of display panels are disposed so as to overlap each other and which displays an image on each of the plurality of display panels. The liquid crystal display device includes a first display panel; and a second display panel disposed so as to overlap the first display panel. The second display panel includes a first substrate on which a source line, a gate line, a thin film transistor, and an organic insulator are formed, a second substrate disposed opposite to the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate, a first spacer is formed in the first substrate to hold a distance between the first substrate and the second substrate. The first spacer and the organic insulator are made of a positive photosensitive resin.

Liquid crystal display device and the method of manufacturing the same

The present invention is intended to control the color temperature of white exhibited by a liquid crystal display device. White is produced when light waves emitted through pixels associated with three colors of red, green, and blue have maximum intensities. The amounts of light emitted through the respective pixels are controlled by differentiating the shapes of the pixel electrodes disposed at the respective pixels from one another. Thus, the color temperature of white is controlled. Otherwise, the shapes of interceptive films disposed at the respective pixels are differentiated from one another in order to control light waves emitted through the respective pixels. Thus, the color temperature of white is controlled. The interceptive film may be shaped like the pixel electrode. Otherwise, the interceptive film may be realized with an interceptive pattern other than that of the pixel electrode or one of openings bored in a black matrix.

Display device

A liquid crystal display device comprises: a first display panel displaying a color image; a second display panel displaying a monochrome image; and an image processor generating first image data corresponding to the color image and second image data corresponding to the monochrome image based on an input video signal. The image processor generates the first image data and the second image data such that a graph representing transmittance of the first display panel for input gradation corresponding to the input video signal and a graph representing transmittance of the second display panel for the input gradation corresponding to the input video signal intersect each other at predetermined input gradation.

A liquid crystal display device includes: a first display panel; and a second display panel opposing to the first display panel. Each of the first and second display panel includes a plurality of source lines, a plurality of gate lines, a plurality of thin film transistors, and a plurality of pixel electrodes electrically connected to corresponding one of the thin film transistors. In a second display panel, at least two thin film transistors are electrically connected to a same second source line and a same second gate line.

Liquid crystal display

A liquid crystal display device includes: a first display panel displaying a color image, a second display panel that is disposed farther away from the observer with respect to the first display panel and displays a monochrome image, and an image processor that generates color image data and monochrome image data. The image processor includes an extension filtering unit that performs extension filtering on first monochrome image data, which is made monochrome using a maximum value in a value of each color expressing color information included in the input video signal. The extension filtering unit performs the extension filtering on the first monochrome image data using a large filter size in a larger luminance difference region, and performs the extension filtering on the first monochrome image data using a small filter size in a small luminance difference region.

A display device includes a primary display area which comprises a first display area and a second display area which is unique from the first display area, a control unit configured to display an image in the primary display area, an image signal generating unit configured to generate display data based on externally input image data for a single image. The image signal generating unit comprises a memory which stores display-position information indicating a display location of a first image displayed in the primary display area. The display data comprises first and second display data to be displayed in the first display area and the second display area, respectively. The first display data is generated based on the externally input single image data and the display-position information. The control unit is configured to cause a first image to be displayed in the first display area based on the first display data.

The present invention provides a display method realizing reduction in a moving picture blurring by forming one frame by two fields of different luminance, in which increase in an unapplied voltage due to shortening of data voltage write time is suppressed. A gate voltage is applied in a light field for a period of time which is twice as long as scan line selection time, thereby decreasing an unapplied voltage. On the other hand, a gate voltage is applied normally in a dark field for the scan line selection time, so that the case where the unapplied voltage increases is eliminated. As a result, an image with high reproducibility can be obtained.
