Abstract: Provided is a display device. The display device includes a first base portion, a second base portion facing the first base portion, a light emitting layer disposed on one surface of the first base portion and emitting first light, a first wavelength conversion pattern disposed on the light emitting layer and converting the first light into second light having a different wavelength from the first light, a first color filter overlapping the first wavelength conversion pattern on one surface of the second base portion and spaced apart from the first wavelength conversion pattern, and an air layer interposed between the first wavelength conversion pattern and the first color filter.

Abstract: A display device comprises a first substrate including a first contact hole, a first barrier insulating layer disposed on the first substrate and including a second contact hole, a fan-out line disposed in a first metal layer on the first barrier insulating layer, the fan-out line including a protruding part inserted in the second contact hole to protrude from below the first barrier insulating layer, and a recessed part formed by the second contact hole, an etching electrode disposed in the recessed part of the fan-out line, a second substrate disposed on the fan-out line and the etching electrode and including a third contact hole, a display layer disposed on the second substrate, and a flexible film disposed below the first substrate and inserted in the first contact hole to be electrically connected to the protruding part of the fan-out line.

Abstract: A drilling and through-wall fire extinguishing device comprises a main water turbine, a forward and reverse commutator, a reducing sleeve, a hollow drill bit, a handwheel booster, a guide rail, a water separator, a vice water turbine and a high pressure water pump. The handwheel booster is connected with the main water turbine, the main water turbine is drivingly connected with the hollow drill bit through the forward and reverse commutator, the reducing sleeve is arranged between the hollow drill bit and the forward and reverse commutator, and the main water turbine and the forward and reverse commutator are fixed on the guide rail; and fire-fighting pressure water is fed by the water separator, a first water outlet of the water separator is communicated with the main water turbine, a second water outlet is communicated with the vice water turbine, and the vice water turbine is drivingly connected with the high pressure water pump.
