[0002]

2. Description of the Related Art Currently, a display pattern of a liquid crystal panel is designed on a computer by using a general-purpose two-dimensional CAD (computer-aided design) system.

Here, in the manufacturing process of the liquid crystal panel,
In order to bond the glass substrate for the segment electrode and the glass substrate for the common electrode, which are the bases of the liquid crystal panel, to each manufacturing apparatus, they are put into each other, but at this time, a displacement occurs between the two glass substrates. The magnitude of the deviation (deviation amount) that occurs at this time is different for each manufacturing apparatus.

Therefore, when performing the simulation of the bonding process of the glass substrates, it is necessary to consider the deviation amount peculiar to each manufacturing apparatus. Therefore, conventionally, the designer has performed the manufacturing simulation while predicting the deviation amount of the glass substrate for each manufacturing apparatus.

Then, the overlapping portion extracting means moves and rotates the electrode figure and the electrode pattern of one of the glass substrates based on the displacement amount to extract the overlapping portion with the electrode figure and the electrode pattern of the other glass substrate.

Thus, the display pattern design system for a liquid crystal panel described above is based on the electrode figure and the electrode pattern of the glass substrate and the amount of displacement between the two glass substrates in the glass substrate bonding step. Lighting simulation can be performed. Then, the lighting shape of the overlapping portion is compared with a normal one, and the lighting shape of the liquid crystal panel in a state where the glass substrate is displaced is corrected by correcting the electrode figure and the electrode pattern so that the lighting shape becomes a normal lighting shape. The display pattern design of the liquid crystal panel considering the displacement of the glass substrate can be performed easily and highly accurately.

The amount of deviation that occurs is stored.

As a result, the deviation amount parameter of the glass substrate, which is set when performing the lighting simulation of the liquid crystal panel, can be selected by selecting the manufacturing apparatus name of the glass substrate bonding step without paying attention to the details of the contents. The deviation amount parameter can be set only by reading from the amount storage means.

Therefore, by setting the electrode pattern and the electrode pattern of the glass substrate and the deviation amount generated between the two glass substrates in the glass substrate bonding process in the display pattern design system of the liquid crystal panel, It becomes possible to more easily design the display pattern of the liquid crystal panel with high accuracy in consideration of the shift.
