を有するものであった。In the past, liquid crystal display panels (LCDs) were commonly used as reflective types, such as in calculators and watches, but with the recent appearance of color LCDs such as the GH type, in some cases they have been used as transmissive types. It may be preferable to use it for display purposes. Furthermore, due to the characteristics of LCDs, their responsiveness at low temperatures is inferior to that of other devices, so when applied to automobile instruments, etc., auxiliary means such as heaters are often required. If it is formed on an electrode substrate, it may not be possible to obtain a desirable color due to its reflection or body color, or in severe cases, the electrode substrate may be damaged due to the rapid temperature rise of the Nesa heater. .
本発明の目的は上記欠点を改良した複合表示パネルを提

られる。According to the present invention, in a composite display panel having a structure in which a white transparent resin having thermal conductivity is interposed between a liquid crystal display panel and a fluorescent display tube, a transparent conductive film provided in the fluorescent display tube is used. A composite display panel is obtained which is characterized in that it can be used as a heater.
上記欠点を改良するものとして白色透光性樹脂を介して
熱を与える方式がある。第１図、第２図にこれらの構造
を示す。To improve the above drawbacks, there is a method of applying heat through a white translucent resin. These structures are shown in FIGS. 1 and 2.

16' is one electrode substrate of the LCD, 17 is a seal for the LCD, 18 is a liquid crystal, and 19 is a NESA heater.

In this case, in order to obtain the desired color, electrical means (, ji, It is easy to obtain red, green, blue or a mixture of these colors as a backlight.

The aim is to improve response characteristics at low temperatures.

' could be damaged. Furthermore, in order for the Nesa film to function as a heater, it is necessary to obtain a low resistance of several Ω/mm, which inevitably results in a thick film, which causes the reflection of light and the film's body color to change. It gave a shadow to the display, which had an undesirable effect on the display.
第２図は、この欠点をなくす為の改良された構造の１例

同じ番号は第１図と同じ機能を有するものとする。FIG. 2 shows an example of an improved structure to eliminate this drawback. Throughout FIGS. 2 and 3, the same numbers as in FIG. 1 have the same functions as in FIG. 1.

どの手法で形成する事が出来る。In FIG. 2, reference numeral 21 denotes a white diffuser plate, which is made of a transparent resin and has good thermal conductivity. The Nesa film 19 is formed on the surface of 11', and a current is passed through it to generate heat, thereby raising the temperature of the liquid crystal 18 by 21. The light from the phosphor layer 14 that emits desired light by the electrons from the filament 13 is passed through 19 and diffused by 21 to constitute a backlight for an LCD. This place-
@21 may be made of a light-transmitting material that is white, has a diffusion effect, and has good thermal conductivity, and can be formed by a method such as screen printing using, for example, olefin-based powder or silicone grease.

熱衝撃によるＬＣＤ基板の破損はなく、当然の事乍らネ
サ膜の色や反射による表示への悪影響も皆無であった。In such a configuration, the Nesa film 19 is formed on the surface of 11', and the heat generated therefrom is transmitted through 2], so that the LCD is not subjected to a sudden thermal shock and is not damaged. Never. Further, since the element 19 is held between 21 and 11', it has the advantage that there is no adverse effect on the display caused by the reflection of the cinematography film or the body imager 2-. In this example, olefin compound 832MT is used as resin 21, 8Ω/mouth Nesa heater is used as 19, and 16.16'
Soda glass with thickness t== 1.2 mm is used for 11', soda glass of 2 mm is used for 11', and L) C12 is used at both ends of 190.
When V was applied, the liquid crystal temperature of 18 changed from -30℃ to 0.
It took about 4-5 minutes to reach temperature. According to the configuration of this example, there was no damage to the LCD substrate due to thermal shock, and as a matter of course, there was no adverse effect on the display due to the color or reflection of the Nesa film.
この例では、２１としてスクリーンプリント法による樹
脂の拡散層を用いたので、通常の拡散板（例えば、１例

）に比ベコストが安くなる利点を挙げる事が出来る。In this example, a resin diffusion layer made by screen printing was used as 21, which has the advantage of being cheaper than a normal diffusion plate (for example, a structure in which a diffusion film is attached to a thin polystyrene plate). I can do it.

るい目的には使用する事が出来る。However, even in the structure shown in FIG. 2, an increase in cost is unavoidable because the Nesa film is formed as 19 on the outer surface of the fluorescent display tube. The present invention improves this point. In other words, the numeral 19 in Fig. 2 has been eliminated, and the NESA film, which was originally provided in the fluorescent display tube for electrostatic shielding, has been applied with a lower resistance value, as shown in Fig. 3, so that it can also be used as a heater. is. With this method, heat is transferred to the liquid crystal display panel through the glass plate of the fluorescent display tube and the white translucent resin, so the thermal efficiency is lower than the example shown in Figure 2. It can be used for casual purposes.
