Abstract

(57) [Summary] [Purpose] The present invention aims at a liquid crystal cell with an inner heater, which has good workability and looks good. A liquid crystal cell having a heater layer 4 on the inner surface is characterized in that a silver paste 7 for a bus bar portion for a heater is sandwiched between two glass substrates 1 and 2 to take out an electrode.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid crystal cell with an inner heater used in a liquid crystal cell having a heater layer on the inner surface.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 3, a heater ITO layer 4, an insulating film layer 5, and a drive ITO layer 3 are formed in this order on the inner surface of the lower glass substrate 2, and the inner surface of the upper glass substrate 1 is formed. A drive ITO layer 3 is formed, a sealing material 6 is further arranged between the upper and lower glass substrates 1 and 2, and electrodes are taken out by applying a silver paste 7 by hand after completion of the cell.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional technique, A. Since the silver paste is applied by hand, there is a problem that it does not look uniform and looks bad.

B. Further, since the silver paste is manually applied after the cell is completed, there is a problem that workability is poor.

Therefore, the present invention has been devised in view of the problems of the above-mentioned conventional techniques, and an object thereof is to provide a liquid crystal cell with an inner heater, which has good workability and good appearance.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the liquid crystal cell with an inner heater in the present invention, in a liquid crystal cell having a heater layer on the inner surface, the silver paste of the bus bar portion for the heater is sandwiched between two glass substrates to form an electrode. It is characterized by taking out.

[0007]

[Action]

 As shown in Fig. 2, silver paste is applied and placed on the lower glass substrate while the liquid crystal cell is being manufactured. This silver paste is applied with a pop-out silver paste that is slightly popped out at the design stage. The pop-out amount of this pop-out silver paste is preferably 1 mm or less.

[0008]

【Example】

 An embodiment will be described with reference to FIG. 1 to FIG. 2. The liquid crystal cell is a liquid crystal cell having a heater layer on the inner surface, that is, on the inner surface of the lower glass substrate 2, a heater ITO layer 4, an insulating film layer 5, The driving ITO layer 3 is formed in this order, the driving ITO layer 3 is formed on the inner surface of the upper glass substrate 1, and the upper and lower glass substrates 1 and 2 are sealed with a sealant 6.

Further, the silver paste 7 of the bus bar portion for the heater for taking out the electrodes is arranged outside the seal material 6 so as to be sandwiched between the two upper and lower glass substrates 1 and 2.

As shown in FIG. 2, the silver paste 7 is applied and placed on the lower glass substrate 2 during the production of the liquid crystal cell. However, at the design stage, the silver paste 7 is slightly ejected and the extruded silver paste 71 is applied. ing.

The amount of the protruding silver paste 71 is preferably set to 1 mm or less.

[0012]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. A. The workability of applying the silver paste at the time of taking out the electrode is improved, and the appearance can be improved.

B. Since the silver paste is not applied manually, the applied amount can be kept constant and the product level can be stabilized.
