摘要： PROBLEM TO BE SOLVED: To provide a pattern layout apparatus for liquid crystal display which can surely form a spacer at a necessary part by greatly shortening the design period and improving the design efficiency. SOLUTION: An arrangement region where a spacer column pattern of an array substrate pattern needs to be formed by using a graphic processing means is specified rectangularly by an arrangement region specifying means. An inhibition region in the arrangement region where the spacer column pattern needs to be formed is specified rectangularly by an inhibition region specifying means. An region which is not the inhibition region in the arrangement region is divided into rectangles to form a plurality of generation region groups by a generation region forming means. The generation regions are divided into rectangles and vertex coordinates of the rectangles of generatable areas are stored in a storage device such as a file; and the coordinate file is used to generate spacer column patterns in matrix by a spacer arrangement means.

摘要： PROBLEM TO BE SOLVED: To provide a pattern layout device which easily copes with the change of production stages or a design method and easily copes with the pattern change meeting a design condition also.
SOLUTION: An arbitrarily drawn original pattern is read out from a storage device 26 by a fundamental pattern extraction means 25. The read-out original pattern is designated to an area having a prescribed area to extract a fundamental pattern. A parameter operation means 27 uses data of the read-out fundamental pattern to recognize element patterns constituting the fundamental pattern respectively. Parameters of individual recognized element patterns are obtained. Rules to execute the processing which recognize individual element patterns respectively and the processing which obtains parameters of individual element patterns are described in rule files 29a to 29f on a computer. At each time of obtaining parameters, the parameter operation means 27 reads out corresponding rule files 29a to 29f to execute a prescribed processing.

摘要： PROBLEM TO BE SOLVED: To provide a pattern layout device for which an improvement in a design accuracy, reduction in a design period, and decrease in errors are aimed at. SOLUTION: A required design specification when designing a reticle, is inputted (11) to a computer configuring a CAD system. The CAD system uses pattern data set beforehand, and creates (12) a detailed pattern of an entire array substrate based on the design specification inputted. Reticle division line is set (13) from this pattern of the entire array substrate and the design specification inputted. Relation between the pattern of the entire array substrate and the division line (14) is judged (14), and if necessary, it is judged which part of the pattern of the entire array substrate the division line that reestablishes (15) of the division line and corrects the pattern of the entire array substrate (16) passes through. If the problem is lost in the division line, the reticle pattern is cut out (17), and each of the divided reticles is stored (19) which are processed with the pattern treatment (18) for a multi-exposure area of a reticle pattern at the same time.

摘要： PROBLEM TO BE SOLVED: To efficiently extract a parameter required for calculating the yield from a pattern by finding the widths and lengths of individual divided patterns on the basis of the lengths of all width candidate patterns and the lengths of length candidate patterns. SOLUTION: The kind of the yield desired to be found, the name of a layer to form wiring, the minimum and maximum line widths of wiring and an extraction step width between these widths are inputted as initial setting (step 21). Corresponding to the yield desired to be found, the pattern of an extraction object is converted and a value required for calculating the yield is generated (step 22). The divided patterns set to the width of a prescribed step number between the minimum and maximum line widths set by initial setting in the step 21 and the width candidate and length candidate patterns corresponding to these respective divided patterns are individually generated (step 23). The width and length of a wiring pattern as the extraction object are extracted while using the found width candidate and length candidate patterns (step 24) and the result is outputted to a file (step 25).

摘要： PROBLEM TO BE SOLVED: To improve the display quality by making a common electrode low in resistance and reducing reflected light from a light shield member, and preventing switching characteristics from decreasing and the voltage of the common electrode from varying. SOLUTION: While reflected light of a light shield film 24 is reduced by interposing an insulating film 46 between the light shield film 24 and common electrode 50 to prevent characteristics of a TFT 22 from decreasing owing to a light leak current, the coupling capacity between the light shield film 24 and common electrode 50 is increased and then the resistance value of the common electrode 50 is reduced by electrically connecting the light shield film 24 and common electrode 50 to each other at the peripheral part of a display area 'A' to prevent the potential of the common electrode 50 from varying owing to coupling with a signal line, thereby suppressing an uneven display due to crosstalk, etc.
