Abstract

A LCD device prevents image quality degradation caused by the gap non-uniformity in the display region with a simple measure. A TFT substrate and an opposite substrate are coupled to each other with a sealing member in such a way as to form a gap therebetween. A liquid-crystal layer is formed in the gap. Spacers are arranged in the liquid-crystal layer. The TFT substrate has a display region defined to include the pixels and a non-display region formed outside the display region. The non-display region is located between the display region and the sealing member. The spacers are located in a first part of the liquid-crystal layer corresponding to the display region while no spacer being located in a second part of the liquid-crystal layer corresponding to the non-display region. A depression for receiving extra liquid crystal may be additionally formed in the gap.
