A process to produce ethylene polymers is provided. The locking ring can include a closed edge zone and a circumferentially interrupted engagement zone, wherein the circumferentially interrupted engagement zone is proximal to the locking groove and the closed edge zone is distal from the locking groove. The device has a two-part construction in which the more expensive electronic components are housed in a reusable portion and the fluid delivery components are housed in a separable disposable portion. A sealing section for sealing the liquid crystal of the liquid crystal layer is provided while enclosing the display area between the glass substrate and the counter substrate. The AHB-to-HTB bus bridge provides a means for the interfacing these two separate AHB buses allowing communication between them and securing data integrity. An alignment layer and a seal pattern are formed to overlap to reduce a width of a bezel, and one or more alignment layer spreading preventing means are formed to prevent a degradation of adhesive strength between the seal pattern and a substrate due to the characteristics of the alignment layer.
