Title: Liquid crystal display device
Inventor: YANAGAWA KAZUHIKO
IPC: G02F1/1368
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent decrease in the transmittance for light or decrease in the contrast by controlling the intensity of an electric field in the border between regions having different directions of electric fields to be almost same as the intensity of the electric field in both regions. SOLUTION: The running directions of electrodes are varied with a virtual line α as the border so that the directions of electric fields generated between a pixel electrode 5 and a counter electrode 4A are different from each other. The side line of the pixel electrode 5 in the bent part nearer to the counter electrode 4A forms an angle θ5, and this part is formed into an arch around the bent point 0 as the center of the counter electrode 4A nearer to the pixel electrode 5. By forming the structure, the whole electric field generating region EA between the pixel electrode 5 and the counter electrode 4A where light can be transmitted has a same width (the shortest distance 1 between the electrodes and it corresponds to the direction of the electric field) along the longitudinal direction. Therefore, the intensity of the electric field in the electric field generating region in the aforementioned bent part is controlled to be almost equal to the intensity of the electric field in the electric field generating region in other part.

Title: Waveform shaping circuit
Inventor: OOYA TAKASHI
IPC: H03K5/13
Filed: 1988-05-02
Abstract: PURPOSE:To simplify the numerical relation of a circuit constant which sets the time change of an output potential with respect to an input potential, to enlarge a setting range and to improve setting precision by shaping a waveform through the use of the linear time change of a voltage on conditions that a constant current is caused to flow in a capacitor. CONSTITUTION:A comparator 31 compares first and second input potentials Vi1 and Vi2, and outputs the potential of a polarity in correspondence with the compared result. A resistance 41 and a current mirror circuit 51 converts the output potential of the comparator 31 into the first current corresponding to the polarity, and a resistance 42 converts the output potential of the comparator 31 into a second current which in a reverse direction with respect to the first current. The first and second currents charge and discharge the capacitor 53 and therefore the potential of one terminal in the capacitor 53 linearly changes. When the potential of the terminal is compared with a reference potential in a comparator 32, the output potential Vo whose waveform is shaped can be obtained. Since the potential of one terminal in the capacitor 53 linearly changes, the time change quantity of the waveform can easily be set, and the setting range can be enlarged, whereby the setting is precisely attained.
