DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a liquid crystal display according to the present invention and an apparatus having the same will be described in detail with reference to FIGS. Here, FIG. 1 is a view showing one embodiment of the liquid crystal display according to the present invention, FIG. 2 is a view showing another embodiment of the liquid crystal display according to the present invention, and FIG. FIG. 11 is a view showing still another embodiment of FIG. FIG. 4 is a diagram showing an example of a portable terminal device as an example of a device having a liquid crystal display according to the present invention. FIG. 5 is a view showing a manufacturing step of the liquid crystal display according to the present invention.
Shows the state of movement and adjustment of the position of the display panel A and the liquid crystal storage container 13, and FIG. 5B shows that the liquid crystal material in the storage container 13 is injected into the inside from the injection hole 12 of the display panel A. It is a figure showing a situation.

In the liquid crystal display shown in FIG. 1, a display panel A as one unit base is composed of a plurality of (here, two) display cells (a1, a2) and cell seals (b1, b2, b3) surrounding the periphery. It is integrated and one-sided. In this configuration, there are two types of display cells on the same silicon substrate and one window is formed. The upper rectangular display cell a1 is surrounded by a linear cell seal, and is configured to be independently separated from the lower display cell a2 at the cell seal b3. The display panel A of the liquid crystal display is a single unit base, and has a rectangular shape as a whole, and its outer periphery is covered by cell seals (b1, b2), and the upper display cell a1 and the lower display cell a2 are covered by the cell seal b3. It is formed so as to be linearly divided.

The liquid crystal display of the present invention can be composed of two display cells (a1, a2) having different properties on one display panel A. By doing so, it is possible to change the resolution and the driving method of the display, respectively, and it is also possible to use a transmissive material or a reflective material properly. In addition, a transmission type TFT (Thin Film Transistor) color LCD made of polycrystalline Si, a reflection type B / W-STN-LCD, or the like can be appropriately selected, and each can be separately applied to a display cell. In addition, the liquid crystal material can be used while being changed depending on the characteristics such as the orientation of each liquid crystal material.

The two display cells (a1, a2) are divided by being surrounded by cell seals (b1, b2), and if each is controlled in an independent mode, a multifunctional and abundant screen display can be performed more efficiently. It can be driven practically, and separate contents can be displayed for each cell screen.
In addition, by turning off the power of the cell screen that does not need to be displayed, it is possible to design such that battery consumption can be suppressed.
At this time, it is convenient that the two independent display cells are separately provided with backlights.

An example of two-screen independent driving is as follows. The first display (display cell a
1) displays soft key usage and still image information (based on text, icons, etc.), while the second display (display cell a2) displays high resolution, full color, and sufficient for moving image display. High-quality full-color information display can be performed using an image having a high expressive power that requires a faster response time. If you compare it to the traditional separate display here,
According to the present invention, the display panel can be manufactured as a display panel having one unit base, the configuration, structure, housing, assembly, and the like can be made simpler and more compact, and can be manufactured with one connector.

Although the embodiment shown in FIGS. 1 to 3 only shows one having two display cells, it may have three, four or more display cells, and the area and distribution of the display cells are appropriately designed.
