ABSTRACT:
The method of the present invention includes the steps of: (A) providing a first substrate, and a second substrate, wherein the first substrate includes a first light shielding layer provided within a non-display region, the first light shielding layer including a light-transmitting portion provided near an outer boundary of the first light shielding layer, the light-transmitting portion comprising a recess or an opening; (B) drawing a seal pattern with a sealant, the seal pattern being drawn outside the first light shielding layer so as to surround the display region, comprising the substeps of: (B1) beginning application of the sealant near the light-transmitting portion, (B2) applying the sealant along an outer periphery of the first light shielding layer, and (B3) forming a junction with the sealant having been applied near the light-transmitting portion; (C) applying a liquid crystal material within the display region surrounded by the sealant; (D) attaching the first substrate and the second substrate; and (E) performing light irradiation from the first substrate side to cure the sealant.
