A distance between a liquid crystal display panel set on a lower support mechanism and a front window set on an upper support mechanism is accurately determined by a stopper. An ultraviolet irradiation mask is provided on the front window. A part of the ultraviolet curable resin corresponding to a transmission pattern of the ultraviolet irradiation mask is temporarily cured through ultraviolet irradiation. The temporarily adhered structure of the liquid crystal display panel and the front window is taken from an attachment device to be left standing for a predetermined time period on a tray until an area and a thickness of the ultraviolet curable resin reach respective predetermined values. The ultraviolet light is then irradiated to an entire surface of the ultraviolet curable resin to finalize the adhesion. The time for which the attachment device is occupied is short, thus improving an operation rate of the device.

Display device with front window and manufacturing method thereof

An object of the present invention is to provide a display device where a display panel and a transparent cover which are pasted together can be separated from each other without breaking the liquid crystal display panel and the transparent cover. The present invention provides a display device having: a liquid crystal display panel having a liquid crystal layer sandwiched between a first substrate and a second substrate which is provided on the viewer side relative to the first substrate; a polarizing plate provided on the above described liquid crystal display panel on the above described viewer side; a viscous film pasted on the viewer side relative to the above described polarizing plate; and a transparent cover pasted on the viewer side relative to the above described viscous film, wherein the above described viscous film is made up of a multilayer body of gluing agents.

Display device with multilayer body having at least one layer of a gluing agent

A liquid crystal display device includes a liquid crystal display panel having a first substrate, a second substrate disposed on an observer side of the first substrate, and a liquid crystal layer sandwiched between the first substrate and the second substrate, and a transparent cover affixed by a first bonding member to a surface of the liquid crystal display panel on the observer side. The transparent cover has an optical member affixed by a second bonding member to a surface of the transparent cover facing the second substrate, and when viewed in plan, an edge of the transparent cover and an edge of the optical member protrude outside the second substrate.

Liquid crystal display device

To provide a liquid crystal display device in which it is possible, with a simple configuration, to avoid a bright spot defect caused by a polishing flaw, called a dimple, formed in a surface of an observer side substrate of a liquid crystal display panel. A liquid crystal display device includes:

The present invention is directed to providing a technology for display devices where a transparent cover is pasted on a display panel according to which inconsistencies resulting from expansion of the polarizing plate in the vicinity of an end portion caused by moisture can be prevented, and the adhesive can be prevented from sagging when the display panel and the transparent cover are pasted together. A display device according to the invention is provided with: a liquid crystal display panel having a first substrate, a second substrate provided on the viewer side of the above described first substrate and a liquid crystal layer sandwiched between the above described first substrate and the above described second substrate; and a transparent cover pasted on the surface of the above described liquid crystal display panel on the above described viewer side using an adhesive. The above described liquid crystal display panel has a polarizing plate between the above described second substrate and the above described transparent cover. The above described adhesive covers the entirety of a side of the above described polarizing plate, and the form of the outer periphery of the above described adhesive in a plane is uneven.
