Abstract
A method for connecting display panel substrates comprises the following steps. Firstly, a first substrate and a second substrate, whereon sealant material is disposed so as to form a waste region in the inner side region of the edges of the first and second substrates, are aligned in position and held. Thereupon, a spacer having a thickness substantially equal to a prescribed cell gap is inserted into the waste region between the first and second substrates. Next, the cell gap is determined by pressing the first and second substrates. The sealant material is then hardened, whereupon the spacer is withdrawn. In this connecting process for fabricating a display panel, the cell gap can be set readily and precisely to a high degree of accuracy.
