Field of the Invention The present invention relates to a ferroelectric liquid crystal cell applied to a display or the like, and more particularly to a ferroelectric liquid crystal cell using an AC stabilization method. The present invention relates to a ferroelectric liquid crystal cell which has a uniform temperature distribution by forming a predetermined resistance distribution on an electrode for controlling the liquid crystal, thereby enabling uniform drawing.

液晶セルが提案されている。[Prior art] Conventionally, a liquid crystal in which the dielectric anisotropy Δε of liquid crystal molecules is negative is A.
C. A ferroelectric liquid crystal cell using an AC stabilization method, which utilizes a phenomenon that an apparent tilt angle is increased when an electric field is applied, has been proposed.

There is an advantage that the brightness in the display state is increased by about two to three times as compared with the driving method (spray driving method) utilizing the above.

う問題点があった。[Problems to be Solved by the Invention] However, the dielectric constant of a ferroelectric liquid crystal material that can be used for a ferroelectric liquid crystal (FLC) cell using an AC stabilization method is generally large. For this reason, in matrix driving, the AC stabilization type FLC cell generates a large amount of heat compared to the spray driving type FLC cell because the charging current to the capacitor formed by the electrode and the FLC increases. It creates a rather non-uniform temperature distribution in the cell in relation to the circuit structure. Therefore, when attempting to paint a FLC cell for AC stabilization of about 75 cm 2 under a normal environment, it is impossible to paint a uniform whole in about 5 to 10 minutes due to uneven temperature distribution. There was a problem that it would.

In a ferroelectric liquid crystal cell for controlling the alignment of liquid crystal, a predetermined resistance distribution is formed in the length direction of the electrode.

ことにより形成される。The predetermined resistance distribution is such that the electrode has a resistance value in the length direction of the electrode in the display portion of the ferroelectric liquid crystal cell and is divided into substantially n equal regions, and S is divided from a side far from the drive source of the electrode. The resistance value R S of the region (S = 1, 2,... N) It is particularly preferable that the resistance distribution is as follows. Such a resistance distribution is formed by, for example, sequentially reducing the cross-sectional area of the electrode or providing the electrode with a plurality of intervals where the width is gradually reduced.

形成される。The electrode usually includes a metal wiring portion having a low resistance and a transparent electrode portion having a very high resistance, and the above-described resistance distribution is formed by configuring only the metal portion as described above.

Therefore, uniform drawing is continued even for a long time. Since the current flowing through the electrode generally decreases as the distance from the drive source (= current source) increases, the resistance value per unit length is distributed so as to increase in the direction away from the current source, so that the heat generation distribution is uniform. Can be done.
