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 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.

摘要： PROBLEM TO BE SOLVED: To provide a pattern layout device for a liquid display device capable of performing a precise liquid crystal device pattern layout in a short time.
SOLUTION: The signal waveform of the electric signal of a liquid crystal pattern layout is drawn in conformation to the liquid crystal pattern layout. A coordinate is extracted from the drawn signal waveform, and the electric signal is converted to a form of signal waveform usable in a liquid crystal circuit simulator by the conversion from the extracted coordinate to time and potential. The electric signal converted to the form of signal waveform usable in the liquid circuit simulator is stored in relation to the liquid crystal pattern layout. Since the liquid crystal pattern layout can be matched to the electric signal, the pattern layout can be designed in a short time without almost making a mistake.

摘要： PROBLEM TO BE SOLVED: To provide a pattern layout method wherein the enhancement of design accuracy, shortening of a designing period, and reduction of design error are made possible by creating an exposure pattern to be transferred onto a substrate by exposure.
SOLUTION: Part of each reticle pattern 15 which does not overlap a light shielding band pattern 16 is extracted, and an exposure pattern 23 to be transferred onto a substrate by an aligner is created. If there is such a defect that the light shielding band pattern 16 overlaps a reticle pattern 15, that can be immediately detected from the exposure pattern 23. Thus, the enhancement of design accuracy, shortening of a designing period, and reduction of design error are possible.
