ABSTRACT:
A liquid crystal display module includes a circuit substrate having at least two II-shaped positioning marks and a pattern line connected with the positioning marks in series, a heat seal having H-shaped positioning marks formed at locations corresponding to the locations of the II-shaped positioning marks and a liquid crystal display unit so that when the circuit substrate is aligned with the heat seal, the lamp connected with both ends of the pattern line is lighted for thereby allowing the aligned state of the circuit substrate and heat seal to be indicated. Therefore, the liquid crystal display module not only reduces the time required for the bonding process and the occurrence ratio of inferior products but also the reliance of products is increased.
