The invention relates to a liquid crystal display (LCD) device, and more particularly to a reflective-transmissive (transmissive-reflective) liquid crystal display device for solving a double-cell gap The problem that arises. [Prior Art] Generally, a liquid crystal display (LCD) device is driven by optical anisotropy and polarization of a liquid crystal. The liquid crystal molecules are aligned by directional characteristics because the liquid crystal molecules each have a long and thin shape. In this aspect, an induced electric field is applied to the liquid crystal, thereby controlling the alignment/direction of the liquid crystal molecules. Therefore, if the alignment direction of the liquid crystal molecules is controlled by the induced electric field, the light is polarized and changed by the optical anisotropy of the liquid crystal, thereby displaying a face image. The liquid crystal display (LCD) device includes: a thin film transistor array substrate, providing a thin film transistor and a pixel electrode; a color filter array substrate, providing a color filter layer; and a liquid crystal layer formed at the Between the two substrates. Recently, an active matrix (AM) type liquid crystal display (LCD) device has great appeal due to its resolution and good kneading quality, wherein the AM liquid crystal display (LCD) device includes and configures In a matrix structure, a thin film transistor, and a pixel electrode. The liquid crystal display (LCD) device does not emit light by itself. As a result, an additional light source, such as a backlight unit, must be used in a liquid crystal display (LCD) device. However, the amount of light passing through the liquid crystal display (LCD) device accounts for about 7% of the total amount of light emitted in the backlight unit. Therefore, a liquid crystal display (LCD) device having high luminance requires a large amount of light so as to increase the power consumption of the backlight unit. In order to provide sufficient power to drive the backlight unit, it is necessary to utilize a huge battery. However, the operating time of a backlight unit using a battery is very limited. In a bright environment, it is difficult to recognize an image displayed on the liquid crystal display (LCD) device. Therefore, a reflection-transmission liquid crystal display (LCD) device has been actively researched and developed which is capable of using both the ambient light and the light emitted from the backlight unit. The anti-200837440' unit pixel-transmission liquid crystal display (LCD) device includes a unit pixel area, wherein: a transmissive portion and a reflective portion.

The pixel electrode I3 is provided with an elongated pattern 1: 3a, and the unit pixel area is divided into fields. Next, the second substrate 3 includes: an R/G/B color light-passing sheet layer % for representing a color; and a common electrode 34 formed on the R/G/B color filter layer. And a germanium layer 36 formed on the common electrode 34 of the reflective portion. a back cover in the reflective portion, the ambient light passes through the liquid crystal reed 50 at the second substrate 3, and then on the reflective sheet U, and passes through the liquid crystal layer again %曰, so the light passes through the working layer 5G two: owe. In the transmission part of Linshi, the second layer of the liquid crystal layer. In this case, due to the cell gap of the reflective portion (the cell gap (G2) of the transmissive portion, the voltage portion of the transmissive portion and the reflective portion is formed into a common electrode at the reflective portion 34 The thickness of the upper cover layer 36 is consistent with each other.
