Abstract: Under a normal environment, when red, green and blue displays are to be performed, the displays are performed singly by a red pixel, a green pixel and a blue pixel respectively, and under a high-illuminance environment, when the red display is to be performed, the display is performed by also shining the pixels other than the red pixel simultaneously, when the green display is to be performed, the display is performed by also shining the pixels other than the green pixel simultaneously, and when the blue display is to be performed, the display is performed by also shining the pixels other than the blue pixel simultaneously, thereby increasing the luminance of a screen. In this case, although the chromaticity of each color is lowered, since the luminance works more predominantly on the image quality under the high-illuminance environment than the chromaticity, image quality degradation does not occur.

Abstract: The invention provides a liquid crystal display device which can reduce the manufacturing cost by reducing the number of parts and simplifying the fabrication and the assembling operation, for the conduction between a metal frame and a color filter substrate. A liquid crystal display panel has a conductive layer on a front surface of a second glass substrate. A panel frame has a side wall part extending along a side wall of the liquid crystal display panel and an upper surface part extending from the side wall part toward a front surface direction of the liquid crystal display panel, integrally formed together. The upper surface part is in contact with the conductive layer of the liquid crystal display panel. A constant potential is applied to the panel frame.

Abstract: A liquid crystal display device includes a touch panel constructed from a single substrate plate and disposed over a liquid crystal display panel. A color filter is disposed over a TFT substrate, and the touch panel is bonded onto the color filter substrate by way of a first adhesion layer. An upper polarizing plate is bonded over the touch panel, and a front window is bonded over the upper polarizing plate via a second adhesion layer. The front window covers a terminal portion which is a portion where only the TFT substrate exists so as to physically protect the portion. Since the upper polarizing plate is disposed over the touch panel, the connection portion of the flexible wiring substrate for the touch panel does not contact with the front window. Thus, the touch panel can be prevented from being strained.
