In the portion of the inner surface of the glass substrate 3 outside the sealing material 7, the color filter F ij and the transparent electrode Y j.
Or, since U is not formed, the height of the portion which becomes the stopper is smaller than the height of the stopper in the effective display area by their thickness (about 0.5 to 1 micron), and the glass substrate 2 has the spacer 6 of It is deformed by an external force so that the intervals are approximately equal to the diameter. Under the influence, the sealing material 7
The glass substrate 2 is convexly curved in the vicinity of the inside. Even in the effective display area apart from the sealing material 7, the cell thickness (thickness of the liquid crystal layer) becomes non-uniform due to the deformation caused by the stress generated in the glass substrate 2. When the cell thickness becomes non-uniform in this way, in the normally black mode of the LCD, the darkness of black depends on the cell thickness d and the refractive index anisotropy Δ of liquid crystal molecules.
Since it is determined by the product of n, it becomes non-uniform and causes deterioration of display quality.
