Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to an improvement in the connection structure between a liquid crystal cell and a circuit component in a liquid crystal display device.

<Prior art> Conventionally, wiring connections between a liquid crystal cell and circuit components in a liquid crystal display device are made by placing the liquid crystal cell on a printed wiring board via a rubber connector, and inserting a chassis ( It had a structure in which it was held in place by a window frame). However, with this structure, the thickness of the entire device could not be made sufficiently thin. A major feature of liquid crystal display elements is that they are extremely thin compared to other display materials such as CRTs, and devices with conventional structures have been unable to take full advantage of the above characteristics of liquid crystal display elements. .

<Objective> The present invention has been made in view of the above-mentioned conventional points, and it is an object of the present invention to provide a novel connection structure for reducing the thickness of a liquid crystal display device as much as possible.

<Example> Hereinafter, an example of a liquid crystal display device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side sectional view of an embodiment of a liquid crystal display device according to the present invention, and FIG. 2 is a partially exploded perspective view thereof. 1 is a liquid crystal cell, 2a is a front polarizing plate, 2b
are respectively attached to the liquid crystal cell 1 with back polarizing plates.
3 is a window frame (chassis) of the liquid crystal display section. A circuit component 4 for driving a liquid crystal is arranged on the back side of the window frame 3, and therefore the window frame 3 constitutes a printed wiring board on which printed wiring is provided on the back side. A terminal portion of the circuit component 4 is formed at the window peripheral portion on the back surface of the window frame 3, and the terminal portion and the electrode 1a of the liquid crystal cell 1 are connected by a rubber connector 5. Reference numeral 6 indicates a fixing fitting for fixing the liquid crystal cell 1 to the window frame 3, and 7 indicates a screw. Further, 8 is a backlight that illuminates the liquid crystal cell 1 from behind. As shown in FIGS. 1 and 2, the rear substrate of the liquid crystal cell 1 has an electrode 1 on the side of the rear substrate.
The size of the front board (segment board) is approximately the same as the size of the window of the window frame 3, and is made smaller. In the structure of the above embodiment, the window frame 3
Since the circuit component 4 is attached to the liquid crystal cell 1, the entire device can be made thinner, and when the illumination body is installed behind the liquid crystal cell 1, the illumination body can be placed without any problem. In the above embodiment, a transmissive liquid crystal display device is shown, but a reflective plate may be provided on the back surface of the back polarizing plate 2b to form a reflective liquid crystal display device. Alternatively, the front polarizing plate 2a may be made larger than the window and attached to the front side of the window frame 3.

<Effects> According to the present invention described above, the thickness can be substantially increased when constructing a liquid crystal display device in which a separately manufactured liquid crystal display cell is integrated with a liquid crystal display cell frame and a drive circuit is connected. It can be manufactured to almost the same thickness as the liquid crystal display cell without having to
This allows the liquid crystal display device to be made extremely thin.
