This application is the U.S. national phase of International Application No. PCT/JP2009/001446, filed 30 Mar. 2009, which designated the U.S. and claims priority to Japanese Application No. 2008-132239, filed 20 May 2008, the entire contents of each of which are hereby incorporated by reference.
The present invention relates to a liquid crystal display device which includes a microlens array and a backlight which is for use in liquid crystal display devices and the like.
In recent years, liquid crystal display devices are widely used as display devices for monitors, projectors, mobile information terminals, mobile phones, and the like. Generally speaking, a liquid crystal display device allows the transmittance (or reflectance) of a liquid crystal display panel to vary with a driving signal, thus modulating the intensity of light from a light source for irradiating the liquid crystal display panel, whereby images and text characters are displayed. Liquid crystal display devices include direct-viewing type display devices in which images or the like that are displayed on the liquid crystal display panel are directly viewed, projection-type display devices (projectors) in which images and the like that are displayed on a display panel are projected onto a screen through a projection lens in an enlarged size, and so on.

Hereinafter, an embodiment of a liquid crystal display device of the present invention is described with reference to the drawings. Note that components which are the same as those of the above-described liquid crystal display device 100′ are indicated by the same reference numerals, and the descriptions thereof are partially omitted.
FIG. 1 is a cross-sectional view schematically showing a structure of a liquid crystal display device 100 of the present embodiment. The liquid crystal display device 100 is a direct-viewing type liquid crystal display (LCD) of an active matrix type. As shown in the drawing, the liquid crystal display device 100 includes a liquid crystal display panel (a liquid crystal display panel with microlenses) 50 and a backlight 30 placed under the liquid crystal display panel 50 (on the surface opposite to the display surface).
