IPC: G02F1/1368
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To form a color filter by means of an easy method while taking an anti-electrostaticity policy by permitting three series source short rings connected to a source bus line to be short-circuited to a gate short ring connected to a gate bus line before forming the color filter. SOLUTION: One end of the gate bus line 104 is short-circuited in order to form the color filter so as to be connected to a gate signal input terminal 107. One end of the source bus line 105 is short-circuited at every third line so as to form the three-group short rings. The respective short rings are connected to source signal input terminals 108-110. The anti-electrostaticity measure is executed by short-circuitting the four input terminals 107-110 before color filter formation. That is, the short rings are not short-circuited except in color filter forming process so that a thin-film transistor is prevented from being distructed by electrostaticity.

Title: Liquid crystal display panel
Inventor: MIZOBATA EIJI
IPC: G09G3/36
Filed: 1991-11-29
Abstract: PURPOSE:To realize high-contrast display with low power consumption by increasing the numerical aperture of one picture element. CONSTITUTION:By making the directions of polarizing plates 8 provided on both sides of a glass substrate the same, liquid crystal is made in a normally black mode. At such a time, it is only at the crossing part of a data electrode 3 and a counter transparent scanning electrode 10 that transmitted light always exists in a part other than a picture element electrode 5. Then, leakage light is not caused by covering the periphery thereof with a light shielding body 13 by several mum so that leakage light from the crossing part and an oblique part may be intercepted. Since a non-linear resistance element 15 has light sensitivity, it is covered with the light shielding body 13. Therefore, the leakage light is prevented without providing the light shielding body 13 on the picture element electrode 5.

Filed: 1989-12-08
Abstract: PURPOSE:To suppress the parasitic capacity of a column select signal line and the current consumption of a read circuit to be increased by enlarging the capacity of a memory by controlling the read circuit and a write circuit by the output of a control signal generating circuit which defines the output of a decoder circuit for column selection as one part of the input. CONSTITUTION:Near a read circuit 5 and a write circuit 6 in a memory cell sub array 2, control circuits 7 and 8 for these circuits 5 and 6 are provided and a column select signal YS is connected to the source of an MOS transistor M3 of these control circuits 7 and 8. Therefore, since the parasitic capacity of the column select signal line YS is decreased rather than the input to the gate of the MOS transistor M3, the starting time and ending time of the column select signal line YS can be shortened. Further, since the plural read circuit 5 and write circuit 6 are selectively operated, a current to flow to a lot of circuits in an unselected state is suppressed to 0. Thus, it is suppressed to increase the parasitic capacity of the column select signal line and the current consumption of the read circuit 8 by enlarging the capacity of the memory.
