Abstract: In a liquid crystal display panel manufacturing method, before two substrates of the display panel are adhered to each other, one of the substrates is subjected to thermal expansion, and after adhesion, the other substrate is subjected to thermal expansion so that the first and second substrates are curved, thereby obtaining a liquid crystal display panel the display surface of which is curved. The liquid crystal display panel manufactured by the above method is relatively low in cost. Further, since the two substrates are not curved forcibly, the gap therebetween is uniform over the entirety of the display surface, ensuring high display quality.
