摘要： The liquid crystal display device, comprising a first liquid crystal cell having first pixels arranged in a matrix shape, the first liquid crystal cell having a first sub-field and a second sub-field, a second liquid crystal cell having second pixels arranged in the matrix shape, the second liquid crystal cell being stacked with the first liquid crystal cell so as to form picture elements, and a circuit for selecting and driving the first pixels and the second pixels in each of the first sub-field and the second sub-field so that a difference between a brightness of the picture elements in the first sub-field and a brightness of the picture elements in the second sub-field is compensated. The circuit is capable of supplying data signals to the first pixels and the second pixels in independent timings so that the sum of the elapsed time after the data signals are applied to the first pixels and the elapsed time after the data signals are applied to the second pixels is substantially the same between the picture elements in the first sub-field and the picture elements in the second sub-field. Thus, the liquid crystal display device with low power consumption and free from the deterioration of picture quality can be accomplished.

The arrangement has a restraining member engaging with the clamp operating member to bend the clamp operating member when the clamp operating member is in a position to position the clamping member in an unclamped position. The clamp operating member is bent by the restraining member when in the unclamped condition to reduce an operating space occupied by the clamp operating member.
