Abstract: PROBLEM TO BE SOLVED: To prevent liquid crystal from being degraded without necessitating a DC neutirizing condition for canceling a DC component by providing a first period and a second period for a unit pixel selection period and making an electric signal selecting the state of one side a pulse signal having a positive polarity when it is seen from a reference level and an electric signal selecting the state of other side a pulse signal having a negative polarity when it is seen from the reference level. SOLUTION: The waveform of a pulse is a waveform in which the ratio between a pulse impressing time and a memory time (that is a neutrizing time) which is sufficient to invert a spontaneous polarization, that is, the relation of (a pulse impressing time/a memory time) is smaller than 1, for example, the waveform of 1/2. It may be sufficient to make the pulse impressing time 50 μsec and the memory time 100 μsec. The driving waveform may be monopolar pulsed waveform and it may be even a rectangular pulse (A), a trapezoidal pulse (B), a three-dimensional function pulse or an exponential functional pulse (C). Moreover, it may be sufficient to add the pulse of a short time being the same sign (D) or a different sign (D) or the combination of them.

Abstract: PURPOSE: To eliminate the need for a correction circuit, reduce the response speed of an element, and prevent the number of processes for manufacturing the element from increasing by controlling in proportion to a signal to be displayed a current flowing through a cathode, when a field emission current between anode and cathode is proportional to luminance. CONSTITUTION: A voltage Va F from a constant-voltage power supply 65 and a voltage Vg F from a constant voltage source 64 are applied respectively to the anode 11 and the gate electrode 13 of a display device. A relation of Va F> Vg F is satisfied. Also, a current source 63 can be voltage-controlled, so that a current value Ia is controlled in proportion to a voltage VK applied via a terminal 17. Even if the characteristic of an element (cold cathode) 16 is varied or if the characteristic of the element 16 is varied due to changes with time, etc., the voltage Vk applied to the current source 63 is set so that a current value at which the required luminance L is obtainable is set, and thus the luminance does not vary.

Abstract: PROBLEM TO BE SOLVED: To provide a reflection type liquid crystal display element and a liquid crystal display device that can realize high moisture resistance and secure long-period reliability by preventing electrode corrosion at a surface part of, specially, a pixel electrode substrate. SOLUTION: A transparent electrode substrate 30 and a pixel electrode substrate 40 are bonded and stuck together with a seal material applied over a peripheral region 102. In this case, the substrates are stuck together so that a pixel electrode 43 and a light shield electrode 45 on the pixel electrode substrate 40 are inside an outer peripheral surface 51A of a seal part 51. If the light shield electrode 45 peels in the peripheral area 102 and so on, the part is not shielded from light, so a driving circuit 44 is also formed preferably inside the seal part 51 in accordance with the light shield electrode 45. Alternatively, light is prevented from being incident on the driving circuit 44 by providing another layer between the light shield electrode 45 and the driving circuit 44 with a light shielding function.

Abstract: PROBLEM TO BE SOLVED: To provide a voltage generation circuit capable of controlling output signals of large amplitude by small amplitude signals without using load resistance, realizing miniaturization and low-voltage operation and reducing power consumption. SOLUTION: A pMOS transistor P1 which is a first level setting means is controlled by precharge signals/Spr and an output node ND1 is precharged to a first level. An nMOS transistor N1 constituting a control circuit is controlled corresponding to the signals of a scanning line SL and a data line DL, signals Sds for controlling the nMOS transistor N2 which is a second level setting means are generated, and by controlling the ON/OFF state of the transistor N2, a capacitor C1 is discharged and the output node ND1 is set to a second level. Since the capacitor C1 keeps the level of the output node ND1 and performs supply to an electrode PD1 which is a load, the objective voltage generation circuit capable of simplifying circuit configuration, being operated at a low voltage and reducing the power consumption is realized.

Abstract: PROBLEM TO BE SOLVED: To improve the image rewriting efficiency and to secure a very high response speed and the very high brightness by transferring the pixel data written into a 1st memory to its corresponding 2nd memory and varying the state of each pixel, based on the pixel data transferred to the 2nd memory. SOLUTION: A memory cell 12 comprises a 1st memory 21, a gate 22, a 2nd memory 23 and a driver 24. The pixel data on the image to be displayed next are written into the memory 21. Then the pixel data written into the memory 21 are transferred to a 2nd memory 23. The pixel data written into the memory 21 are transferred to the memory 23 via the gate 22. Based on the pixel data transferred to the memory 23, the driver 24 is driven. Thus, the driver 24 operates, based on the pixel data stored in the memory 23, and varies the state of each pixel. In such a way, the image rewriting efficiency is improved.
