A barrier system for partitioning a space is formed by panels which interlock with each other to provide a barrier that is fire rated. The interlocking panels are assembled in the barrier in columns which include at least two panels. A first horizontal joint between two panels of the barrier in a first column is vertically offset from a horizontal joint between two panels of the barrier in a second column that is adjacent to the first column at a vertical joint. Each panel is made of a laminated structure including a supporting frame around a core layer, barrier layers on opposed surfaces of the core and skin layers on the barrier layers. Tongue and groove construction interlocks the panels and a locking structure formed by a tapered hook in the groove engaging into a slot of the tongue locks horizontally adjacent panels to each other.

A display device includes: a window including a bending area and a non-bending area; an adhesive layer including a first adhesive portion and a second adhesive portion, wherein the first adhesive portion overlaps the bending area, and the second adhesive portion overlaps the non-bending area; and a display module disposed on the adhesive layer, wherein the first adhesive portion is formed by curing a first resin including a first photoinitiator configured to have an initiation reaction induced by a first light, and the second adhesive portion is formed by curing a second resin including a second photoinitiator configured to have an initiation reaction induced by a second light or a thermal initiator, wherein the second light has a different central wavelength front that of the first light.

Provided is a lower protecting plate of a battery module for an electric car. The lower protecting plate may include a fiber-reinforced plastic composite formed of a lamination sheet including at least one of first and second sheets. The first sheet may include matrix resin and reinforced fiber in the form of long fiber.
