In this liquid crystal display element, an active matrix substrate 1 and a counter substrate 2 are bonded together via a substantially rectangular frame-shaped sealing material 3, and a liquid crystal (not shown) is provided between the two substrates 1 and 2 inside the sealing material 3. It consists of a sealed one. In this case, the right side and the lower side of the active matrix substrate 1 protrude from the counter substrate 2. Hereinafter, these protrusions are referred to as a right side protrusion 1a and a lower side protrusion 1b. Further, the sealing material 3 is arranged outside the display area 4 indicated by a dashed line.

Further, a ring-shaped short-circuit line 11 is provided outside the display area 4 on the active matrix substrate 1 and inside the area where the sealing material 3 is arranged.

It is provided. In addition, a plurality of electrostatic protection elements 13 are connected to the short-circuit line 11 and the data lines 8 on the lower side of the upper side of the short-circuit line 11 and on the upper side of the lower side of the short-circuit line 11 outside the display area 4 on the active matrix substrate 1. They are connected and provided.

Next, a brief description will be given of measures against static electricity in this active matrix type liquid crystal display device. For example, when static electricity is externally charged on the left end surface or the upper end surface of the active matrix substrate 1, the electrostatic protection element 1
2 and 13 are conducted, and the short-circuit line 11, all the scanning lines 7 and all the data lines 8 have the same potential, thereby preventing the thin film transistor 6 from being electrostatically damaged.

Next, a specific structure of a part (the thin film transistor 6 and the electrostatic protection elements 12, 13) of the active matrix type liquid crystal display element will be described with reference to FIG. The thin film transistor 6 includes a gate electrode 21 provided on the upper surface of the active matrix substrate 1, a gate insulating film 22 provided on the upper surface, and a gate insulating film 2
2, a semiconductor thin film 23 made of intrinsic amorphous silicon, a blocking layer 24 provided at the center of the upper surface of the semiconductor thin film 23, and both upper surfaces of the blocking layer 24 and upper surfaces of the semiconductor thin films 23 on both sides thereof. Contact layers 25 and 26 made of n-type amorphous silicon, and a source electrode 27 and a drain electrode 28 provided on the upper surfaces of the contact layers 25 and 26. In this case, the source electrode 27 is
2 is connected to the pixel electrode 5 provided on the upper surface.

The electrostatic protection elements 12 and 13 include a semiconductor thin film 31 made of intrinsic amorphous silicon provided on the upper surface of the gate insulating film 22, a blocking layer 32 provided at the center of the upper surface of the semiconductor thin film 31, and a blocking layer. 32
Contact layers 33 and 34 made of n-type amorphous silicon provided on both sides of the upper surface of the semiconductor thin film 31 and on both sides thereof, and one connection electrode 35 and the other connection electrode provided on the upper surfaces of the contact layers 33 and 34 36. In this case, one connection electrode 35 is connected to the short-circuit line 11 and the other connection electrode 36 is connected to the scanning line 7 or the data line 8.

Next, another specific structure of the active matrix type liquid crystal display device will be described with reference to FIG. An alignment film 41 is provided on the active matrix substrate 1 so as to cover the pixel electrode 5, the data line 8, the electrostatic protection elements 12, 13 and the like inside the region where the sealing material 3 is arranged. A black mask 42, a color filter (not shown), a counter electrode 43,
An alignment film 44 is provided. Then, both substrates 1, 2
Are bonded via a sealing material 3 mixed with a columnar spacer 45 made of glass fiber having a diameter of 3 to 10 μm and a length of about 100 μm, and a liquid crystal 46 is sealed between them. In this case, the alignment films 41 of both substrates 1 and 2
A spherical spacer 47 made of resin and having a diameter of 3 to 10 μm is interposed between 44.

Here, the reason why the materials of the spacers 45 and 47 are different will be described. When the material of the spacer 47 interposed between the alignment films 41 and 44 is glass fiber,
Since they are hardly elastically deformed, if they are arranged on the thin film transistor 6 and the electrostatic protection elements 12 and 13, the thin film transistor 6 and the electrostatic protection elements 12 and 13 will not work when pressure is applied for bonding the substrates 1 and 2. May be crushed and destroyed. Therefore, the spacer 47 is formed of an elastically deformable resin. On the other hand, since the spacer 45 mixed in the sealing material 3 is not disposed on the thin film transistor 6 or the electrostatic protection elements 12 and 13,
In order to further ensure the control of the gap, the gap is made of glass fiber which does not deform elastically.

[0012]

Next, a specific structure of a part of the active matrix type liquid crystal display device will be described with reference to FIG. In this figure also, for convenience of explanation, the same reference numerals are given to the same parts as those in FIG. An alignment film 41 is provided on the active matrix substrate 1 so as to cover the pixel electrodes 5, the data lines 8, and the like inside the region where the sealing material 3 is disposed. In this case, the electrostatic protection element 12,
Reference numeral 13 is arranged outside the alignment film 41, that is, in the region where the sealing material 3 is arranged. On the lower surface of the counter substrate 2, a black mask 42, a color filter (not shown), a counter electrode 43, and an alignment film 44 are provided.

Here, the experimental results will be described. As a spherical spacer made of silica, the compression characteristics are different.
Various types were prepared (hereinafter, referred to as silica spacers 1 to 4). For comparison, a cylindrical spacer made of glass fiber (hereinafter, referred to as glass fiber spacer) and a spherical spacer made of resin (hereinafter, referred to as resin spacer) were prepared. Silica spacer 1
4. The initial diameter of the glass fiber spacer and the resin spacer is about 5 μm.

When the compression properties of the silica spacers 1-4, the glass fiber spacer, and the resin spacer, that is, the relationship between the load and the amount of deformation, were examined, the results shown in FIG. 5 were obtained. As is clear from this figure, the deformation amount is glass fiber spacer, silica spacers 1-4,
It becomes larger in the order of the resin spacer. Normally, the load per spacer in a state where both substrates 1 and 2 are bonded via the sealing material 3 is about 0.2 gf, and therefore the amount of deformation for such a load is important.
Therefore, the deformation amounts of the glass fiber spacer, the silica spacers 1 to 4 and the resin spacer when the load is 0.2 gf are respectively 0.096 μm and 0.12 μm.
m, 0.165 μm, 0.209 μm, 0.5 μm,
0.713 μm.

As a result of comparing the probability of destruction of the electrostatic protection elements 12 and 13 and the thin film transistor arranged under the sealing material in the above sample, the yield was about 70% in the case of the glass fiber spacer. On the other hand, silica spacer 1
-4 and the resin spacer have a yield of 95
% Or more. In particular, with the silica spacers 2 to 4 and the resin spacer, the yield was substantially 100%. However, in the case of a resin spacer, the gap between the two substrates when the active matrix substrate 1 and the counter substrate 2 are bonded to each other is large, which is not preferable. Also,
Also in the case of the silica spacer 4, there is some difficulty in that the deformation amount when the load is 0.2 gf is relatively large, 0.5 μm.

To summarize the above, as spacers mixed into the sealing material 3, silica spacers 1 to 3 should be used in order not to destroy the electrostatic protection elements 12 and 13 and to more surely control the gap. 4 is preferable, in other words, when the load is about 0.2 gf, the amount of deformation is 0.12-0.
Those having a compression characteristic of about 5 μm are preferred. However, a silica spacer 1 having a compression characteristic close to a glass fiber spacer and a silica spacer 4 having a compression characteristic close to a resin spacer are rather less preferred, and the silica spacers 2 and 3 are more preferred.
In other words, a material having a compression characteristic in which the amount of deformation is about 0.165 to 0.209 μm when the load is about 0.2 gf is more preferable.

Further, in each of the above embodiments, the case where the capacitive type as shown in FIG. 7 is used as the electrostatic protection elements 12 and 13 has been described.
