Abstract: A method of producing a display panel using a seal dispenser including a nozzle and discharging sealing material onto the substrate, the sealing material applied onto the substrate having a sealing material cross-sectional area cut along a plane orthogonal to a nozzle moving direction and a spacing between the substrate and a tip of the nozzle being defined as a nozzle gap. The method includes a determining step of determining the nozzle diameter and the nozzle gap corresponding to the target sealing material cross-sectional area based on a linear function that approximates a relationship between a product of a nozzle diameter and the nozzle gap and the sealing material cross-sectional area, and a sealing material applying step executed after the determining step and applying the sealing material onto the substrate through the nozzle having the nozzle diameter determined in the determining step while maintaining the nozzle gap determined in the determining step.

Abstract: A liquid crystal cell includes a first substrate with a plate surface including a display area, a second substrate opposed to the first substrate, a sealant bonding the first substrate and the second substrate together with a cell gap, a liquid crystal layer, a base layer, and a protrusion. The sealant includes a surrounding wail and passage walls. The surrounding wall defines the filling space overlapping the display area and an entrance to the filling space. The passage walls define a passage to the entrance to the filling space to pass a liquid crystal material. The liquid crystal layer is disposed in the filling space. The base layer is disposed on a section of a plate surface of one of the first substrate and the second substrate in the passage. The protrusion protrudes from the base layer toward another one of the first substrate and the second substrate.
