The present invention provides a liquid crystal display device which can enhance quality and reliability of image display by preventing the generation of bubbles in the inside of a liquid crystal display panel and, at the same time, by suppressing leaking of light from an end of a black matrix film. In the liquid crystal display panel which sandwiches a liquid crystal layer between two glass substrates, the liquid crystal layer is surrounded by a sealing material having a predetermined width. On one glass substrate, a black matrix film and an overcoat film are arranged from one-glass-substrate side such that the black matrix film and the overcoat film overlap the sealing material. The black matrix film is, in the widthwise direction of the sealing material, formed into a planar flat black matrix film until a middle position of the sealing material from a side on which the liquid crystal layer is arranged, and is formed into a slit-shaped slit black matrix film from the middle position. Due to such a constitution, an adhesion area between the glass substrate and the overcoat film under an applied region of the sealing material is enlarged and hence, an adhesion strength is increased thus largely enhancing an adhesion strength.

The invention provides a cryogenic liquid pump system, having a first end with at least an insulating lid and motor; a second end, wherein the second end is a pump, said pump comprising an impeller; and a gas release plate upstream of the impeller; and a shaft disposed between the first end and the second end, wherein the motor imparts mechanical energy to the pump through the shaft. Also provided is a method for preventing cavitation of a cryogenic liquid in a cryogenic pump, the method having the steps of constantly maintaining pressure on the liquid in the pump and evacuating gas bubbles that form within the pump.

Provided is a liquid ejecting apparatus for ejecting a liquid, including: a depressurizing pump: a liquid storing chamber which includes an inlet for the liquid and stores the liquid; a first partition wall portion which has flexibility and gas permeability; a first pressure control chamber which is adjacent to the liquid storing chamber with the first partition wall portion interposed therebetween; a pressure control valve which opens or seals the inlet in response to displacement of the first partition wall portion; and a switching valve which is connected to the first pressure control chamber and the depressurizing pump and selects an arbitrary state among a first communication state where the first pressure control chamber communicates with an atmosphere, a second communication state where the first pressure control chamber communicates with the depressurizing pump, and a sealed state where the first pressure control chamber is sealed.

A liquid member ejecting device comprises an ejecting head and a liquid member tank for storing a liquid member and supplying the liquid member to the ejecting head. The liquid member ejecting device further comprises an attracting member for covering nozzles, a first decompressing section which is connected to the first attracting section for decompressing inside of the ejecting head via the first attracting member, a second attracting member for covering the nozzles, and a second decompressing section which is connected to the second attracting member so as to decompress inside of the ejecting head via the second attracting member and inside of the liquid member tank while communicating the liquid member tank. By doing this, it is possible to provide a liquid member ejecting device and method therefor, an electro-optic device, and manufacturing method therefor, and an electronic apparatus which can prevent the manufacturing cost from increasing due to the wasteful use of the liquid member so as to remove bubbles from the ejecting head while realizing a smaller nozzle diameter and finer flow paths.

The invention provides a preparation method of a display panel, the display panel and a display device. The preparation method comprises the steps of forming an inorganic packaging layer on a drivingbackboard through employing a vapor deposition method, and enabling the inorganic packaging layer to comprise a main packaging layer covering a display region and a part of a peripheral region, and apermeation layer extending from the main packaging layer to a direction far away from the display region, forming an inorganic layer at one side, deviating from the driving backboard, of the inorganicpackaging layer, and enabling the inorganic layer to comprise a first inorganic layer covering the main packaging layer and a second inorganic layer extending from the first inorganic layer to a direction far away from the display area, and synchronously etching and removing the second inorganic layer and the permeation layer by adopting the same mask. Therefore, the permeation layer can be removed, the problem of bubbling caused by the permeation layer is solved, and good performance of the FMLOC touch display panel is guaranteed.
