摘要： The thin film transistor comprises source and drain regions, a channel forming region formed between the source and drain regions, a first (main) gate for turning on or off the transistor, and in particular at least one second (sub-) gate for reducing turn-off leakage current. When the n-channel transistor is turned off, for example, a negative voltage is applied to the main gate to form a p-channel layer in the channel forming region under the main gate and a positive voltage is applied to the subgate to form an n-channel layer in the channel forming region under the subgate, for instance, so that a pn junction can be formed between under the main gate and the subgate to reduce the turn-off leakage current. The above-mentioned disclosure can be clearly applied to p-channel transistors. Further, the above four-terminal transistor can be simply modified to a three-terminal transistor by connecting the main gate to the subgate via a diode or a capacitor or by directly connecting the drain region to the subgate. Further, the above three-terminal transistor can be manufactured in accordance with only the ordinary device manufacturing process.

摘要： A polymer dispersed liquid crystal optical device is presented which has optical elements which control reflection, transmission and diffraction of incident light entering the device by adjusting the magnitude of the electrical field applied to the device between a maximum and a minimum limits. An optical element consists of a polymer material having an electrical field-independent refractive index, and a liquid crystal material having an electrical field-dependent refractive index. The optical elements are distributed through the device at specific inter-element spacings, thus enabling to generate reflection of incident light in accordance with Bragg's law of reflection. The inter-element spacings can also be varied by the application of the field, thus enabling to generate reflection of light of a desired wavelength. Such optical elements are ideal for use in full color optical display apparatus of a matrix driven type. Methods for producing the optical device and optical display apparatus are also presented.
