Abstract:
1. A method of manufacturing a liquid crystal panel having a pair of glass substrates formed with a TFT element and a color filter on respective glass substrates and surrounding a liquid crystal holding area by a thermosetting resin between the pair of glass substrates, the method comprising: a first step of forming two or more alignment marks on the respective glass substrates; a second step of coating the thermosetting resin onto one of the glass substrates; a third step of measuring and storing coordinates of the marks formed on the glass substrates; a fourth step of overlapping the two sheets of glass substrates to sandwich the thermosetting resin while positioning the glass substrates such that relative positions of the marks provided on the two sheets of glass substrates are aligned in accordance with previously stored values, storing the positions of the marks and calculating and storing an error between positions of gravitational centers of the two sheets of glass substrates, an inclination between the substrates and a difference between distances between the marks thereof by using a previously stored equation or table; a fifth step of curing the thermosetting resin by heating the two sheets of substrates independently based on said previously stored values for the respective substrates while pressing the substrates together at a predetermined pressure; a sixth step of cooling the glass substrates; and a seventh step of measuring and storing the positions of the marks on the two sheets of glass substrates and storing the error between the positions of the gravitational centers of the two sheets of the glass substrates, the inclination between the substrates and the difference between the distances between the marks using the previously stored equation or table.
