Claim:
An LCD apparatus, comprising: an LCD panel having a color filter for a plurality of color components and having a plurality of pixels each associated with one of the color components of the color filter; and a side lighting-type backlight unit disposed under the LCD panel, the backlight unit including a light guide and a light source disposed at least at one lateral end of the light guide, the light guide directing light emitted generally in a lateral direction from the light source towards the LCD panel thereabove to enable a transmission display of an image data controlled by the LCD panel, the backlight unit further including a reflecting layer on a side opposite to a side facing the LCD panel to reflect light coming towards the reflecting layer from the light guide, the reflecting layer further reflecting ambient light originating from an exterior, passing though the LCD panel and through the light guide, back to the light guide and the LCD panel, thereby enabling a reflection display of the image data controlled by the LCD panel in addition to the transmission display using the light source, wherein the color filter is configured to compensate a change in color spectrum in the ambient light that has passed through the LCD panel and the light guide and that has been reflected by the reflecting layer back to the light guide and the LCD panel so that the color temperature of white display of the LCD panel by the ambient light remains substantially the same as the color temperature of the original ambient light.
