Rigid circuit board for liquid crystal display including cut out for providing flexibility to said board

A method of manufacturing a drive circuit module comprising steps of:

• forming a circuit pattern having a plurality of input terminals and output terminals supported by a flexible insulation film;
• installing a liquid crystal display drive LSI on the circuit pattern on a carrying section;
• providing at least two cutouts spaced from one another on a surface opposite to the surface on which said circuit pattern of said board is formed, said cutouts being in the form of cut grooves;
• and
• bending said module at said at least two cutouts in a direction in which said output terminal surface and said carrying section surface are different from each other.

A method of manufacturing a liquid crystal display device comprising steps of:

• connecting wiring terminals of a TFT board to form wiring terminals connected to a gate electrode wiring and a source electrode wiring of said TFT to an output terminal of a drive circuit module which has a rigid board formed of a hard base material;
• forming a circuit pattern on the board having a plurality of input terminals and output terminals supported by a flexible insulation film;
• providing a carrying section for carrying a liquid crystal display drive LSI on the circuit pattern;
• providing at least one cutout on a surface opposite to the surface on which said circuit pattern of said board is formed, said at least one cutout being in the form of counter boring grooves used for bending said module, thereby making flexible said module in a direction in which said output terminal surface and said carrying section surface are different from each other;
• and
• bending said module at said at least one cutout.
