放電管が構成される。 According to this invention, a liquid crystal display section is constructed by including this glass plate on one side of a common transparent glass plate,
Therefore, a transparent electrode is formed on the surface of the transparent glass plate facing the liquid crystal display section. A fluorescent material layer is formed on the other surface of the transparent glass plate, and the fluorescent material layer is on the inside, and a fluorescent discharge tube is constituted by including the transparent glass plate. In other words, they include a common transparent glass plate, with a liquid crystal display section on one side and a fluorescent discharge tube on the other side.

are arranged, and a liquid crystal substance 14 is sealed between the transparent glass plates 13 and 11. Generally, a transparent electrode 15 is also formed on the inner surface of the transparent glass plate 13. Furthermore, alignment treatment layers 16 and 17 are formed on the inner surfaces of transparent electrodes 12 and 15, respectively. The long axis direction of the molecules of the liquid crystal substance 14 is oriented in a predetermined direction by these alignment treatment layers 16 and 17. The peripheral edges of the transparent glass plates 11 and 13 are sealed with a ring 18 made of glass, epoxy sealant, or the like. Furthermore, a second transparent glass plate 13
A polarizing plate 19 that transmits only light in a predetermined polarization direction is attached to the surface opposite to the transparent glass plate 11. In this way, the liquid crystal display section 20 is configured.

２２はガラス材の板状容器である。 In this invention, a fluorescent material layer 21 is formed on the other surface of the first transparent glass plate 11 over almost the entire surface as shown in the figure. Further, an airtight container 22 is constructed, including the fluorescent material layer 21 therein and using the transparent glass plate 11 as a part of the component. That is, in this example, a transparent glass plate 23 is provided opposite to the transparent glass plate 11, and the transparent glass plates 11, 1
The peripheral edge portions of the transparent glass plates 11 and 23 and the peripheral wall portion 24 constitute one airtight container 22. In other words, the airtight container 22 is a plate-shaped container made of glass.

A fluorescent material layer 28 is also formed on the inner surface of 3.
Further, a metal plate 29 is formed on the outer surface of the transparent glass plate 23 over almost the entire surface, and serves as a light reflecting plate and is connected to the cold cathode 26 to serve as a trigger electrode. The airtight container 22 is filled with an inert gas such as argon.

Note that the reflecting plate 29 may be formed not on the outer surface of the airtight container 22 but on the inner surface, that is, on the inner surface of the third transparent glass plate 23. In this case, the fluorescent material layer 28 is omitted.

応の低下を防ぐこともできる。 As described above, in the liquid crystal display device with a light source according to this invention, the transparent glass plate 11 is used in common, and the liquid crystal display section 20 is formed on one side of the glass plate and the fluorescent discharge tube 25 is formed on the other side. Since the display section and the light source for it are integrated, it can be made compact and is very convenient to handle. In addition, since the first transparent glass plate 11 of the airtight container 22 of the fluorescent discharge tube 25 also serves as the substrate of the transparent electrode 12 of the liquid crystal display section, an additional effect is that the liquid crystal material layer 14 is heated by the heat generated by the fluorescent discharge tube 25. It is possible to warm the liquid crystal material and therefore prevent a decrease in the reaction of the liquid crystal material at low temperatures.
