Method of manufacturing a liquid crystal display device having rectangular close-shape seal members

摘要

A method of manufacturing a liquid crystal device having a first substrate and a second substrate facing each other with a liquid crystal layer interposed therebetween, and a sealing member formed in a peripheral portion of at least one of the substrates. The method includes forming the sealing member, disposing the liquid crystal layer inside the sealing member, and bonding the first substrate to the second substrate. In forming the sealing member, a ring-shaped portion that seals the liquid crystal layer inside the sealing member, a first sealing layer and a second sealing layer that face each other to be separated from each other are formed. In the bonding of the first substrate to the second substrate, a junction portion is formed in which the first and second sealing layers are pressed and joined outside the sealing member so as to form the ring-shaped portion.

1. A method of manufacturing a display device including a first substrate and a second substrate attached to the first substrate via a seal member, the display device having a display region in which a plurality of pixels are aligned, comprising:
a first step of forming a seal member in a seal region of the first substrate, the seal region being positioned around the display region, and the seal member being formed continuously around the entire display region; a second step of attaching the second substrate to the first substrate via the seal member; wherein the seal region has a rectangular closed-shape that surrounds the display region, the seal region having a first side, a second side, a third side and a fourth side, the first side being opposed to the third side, and the second side being opposed to the fourth side, the first step including: a first forming step forming a first continuous seal member in a part of the second side, the first side and a part of the fourth side, a second forming step forming a second continuous seal member in a remaining part of the second side, the third side and a remaining part of the fourth side, wherein the first continuous seal member is not disposed on the third side and the second continuous seal member is not disposed on the first side.
