摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive liquid crystal display device with low power consumption and excellent display quality by disposing a scattering polarizing plate which transmits a polarized light component in one direction from a back light but scatters and reflects a polarized light component in the perpendicular direction to the first component to the opposite direction, and disposing a reflecting member for the scattered light which reflects the scattered and reflected light to the scattering and polarizing plate. SOLUTION: The light emitted from a back light 2 enters the scattering polarizing plate 3, where the polarized light component 11 (S-polarized light) is transmitted forward while scattered a little by the scattering polarizing plate 3. The polarized light component 12 (P-polarized light) is scattered backward by the plate 3. While the polarized component scattered backward is reflected by the inside of the back light 2, the one-component polarized state is partially disturbed, and finally reflected by a reflecting member 6 for the scattered light and then emitted as not only the P-polarized light 16 but containing the S- polarized light 15 from the back light 2. Thereby, the proportion of the S- polarized light is increased, and as a result, the quantity of light entering the liquid crystal 1 is increased and a bright display can be obtd.

摘要： PURPOSE: To decrease the holding power of a sealing wall for substrates and to make a process of disposing the sealing wall in the substrate plane unnecessary by using the adhesion property of a polymer dispersion liquid crystal itself to adhere and hold the surface of first and second substrates and the polymer dispersion liquid layer. CONSTITUTION: A first glass substrate 51 is disposed in parallel to a second glass substrate 52 to face the surface where an electrode is formed at a small distance regulated by a spacer 30 distributed on the substrate 51. The surfaces of the substrates 51, 52 and the upper and the lower surfaces of a liquid crystal layer 40 are adhered on planes by the adhesion property of the liquid crystal layer 40. A sealing wall 55 is formed on a substrate 51 to surround the side faces of the substrate 52 and the side faces of the liquid crystal layer 40 so that the adhesion between substrates 51, 52 is made firm and the liquid crystal layer 40 can be protected from deterioration by the reaction with external air. Thereby, by intently using the surface adhesion property between the liquid crystal layer 40 and the substrates 51, 52, the mechanical load on the sealing wall 55 can be remarkably decreased.

摘要： PURPOSE:To largely modulate a current between a source and a drain by a voltage applied to a gate by composing a semiconductor layer of a pi-conjugate polymer soluble in solvent, and bringing at least one of source and drain electrodes in nonohmic contact with the layer. CONSTITUTION:The width of a depleted layer formed at the side of a soluble pi-conjugate polymer film 4 in a boundary between the film 4 and an insulating film 3 is controlled by a voltage applied between a gate electrode 2 and a source electrode 5, and channel sectional area of an effective carrier is varied. Accordingly, a current flowing between the electrode 5 and a drain electrode 6 is varied. A hetero junction is formed of the electrodes 5, 6 and a semiconductor layer, and when they are brought into nonohmic contact with each other due to its potential barrier, a current between the source and the drain when a voltage is not applied to the electrode 5 is reduced according to the size of the barrier.

摘要： PURPOSE:To facilitate the high speed switching and enable integrating elements, by compounding a semiconductor layer from an organic thin film composed of pi-conjugated polymer and equipping a gate electrode only at the part opposing the part where said semiconductor layer is put between a source electrode and the drain electrode. CONSTITUTION:A semiconductor layer 4 is made of an organic thin film composed of pi-conjugated polymer and a gate electrode 2 is formed only at the part opposing the part where said semiconductor layer is put between a source electrode 5 and a drain electrode 6. pi-conjugated polymer having a heterocyclic five-membered ring is desirable for forming the organic thin film 4 because it fits the characteristic of an FET, has high ability to form a film, and is easy to synthesize; however, any other pi-conjugated polymer is acceptable. This reduces the capacitance between the source and the gate and between the drain and the gate, increases the current switching speed, and enables integrating elements.

摘要： PURPOSE:To enable stable operation and the great change of the conductivity between a source and a drain by the voltage applied from a gate by using a pi-conjugated system macromolecule for the source, the drain and the semiconductor layer which is a current path in a FET. CONSTITUTION:A FET consists of a substrate 1 carrying thereon a metal film 2 for a gate electrode, an insulating film 3, a pi-conjugated system macromolecular film 4 for a semiconductor layer, the pi-conjugated system macromolecular films 10, 11 for a source and a drain and metal films 8, 9 for the lead wires from the source and the drain provided. Here, any pi-conjugated system macromolecule can be used but a pi-conjugated system macromolecule which has a five-membered heterocycle is desirable owing to the characteristics of an FET, the properties of film forming and the easiness of synthesis. Since the pi-conjugated system macromolecule synthesized by an electrochemical polymerization is also generally doped with the anion of a supporting electrolyte, the good properties for the FET element can be obtained.
