In the present embodiment, a sealing agent (50) sealing two substates contains a low melting-point glass material and is adhered to each of a first substrate (10) and a second substrate (20), a barrier rib (60), which is formed in such a manner as to surround the outer periphery of an electronic element (30), is disposed between the sealing agent (50) and the electronic element (30), and between the first substrate (10) and the second substrate (20), and the sealing agent (50) is spaced apart from the barrier rib (60). As a result, a deterioration of the electronic element, caused by the heat produced when sealing, may be prevented while the electronic element formed between the two substrates is protected from moisture and oxygen.

Substantially alkali free glasses are disclosed with can be used to produce substrates for flat panel display devices, e.g., active-matrix liquid crystal displays (AMLCDs). The glasses have high annealing temperatures and Young's modulus. Methods for producing substantially alkali free glasses using a downdraw process (e.g., a fusion process) are also disclosed.

The present disclosure provides a glass panel of a display screen, of which each side bulges outwards gradually with respect to a connection line of opposing ends of the side, with a vertical distance from a point on the side between an end and a midpoint of the side to the connection line of the opposing ends of the side increasing gradually in a direction from the end to the midpoint.

Laminated articles and layered articles, for example, low alkali glass laminated articles and layered articles useful for, for example, electrochromic devices are described.

The present disclosure provides a glass plate including a main surface having a plurality of minute deformed portions which are recesses or projections, wherein, where an average value of lengths of two sides adjacent to each other of a minimum quadrilateral with four right angles surrounding each minute deformed portion is defined as a dimension, an average value of the dimensions of the plurality of deformed portions is 3.2 to 35.5 μm. The glass plate satisfies a condition a1 that a ratio of deformed portions A1 having the dimensions of 0.5 to 3.0 μm with respect to the plurality of deformed portions in terms of number is less than 5%, and/or a condition d1 that a coefficient of variation of the dimensions is 40% or less. This glass plate is suitable for suppressing sparkle and is highly practical, when disposed on an image display device.

The disclosure provides an optically drivable glass device including: a substrate; a windable stacked layer arranged on the substrate, where one end of the windable stacked layer is installed on the substrate, and the windable stacked layer includes a driving layer formed of an ultraviolet rays-sensitive and deformable material, and a flexible substrate layer with a light absorbing or reflecting function, where an initial state of the driving layer is a flat state; and an ultraviolet light source configured to provide the windable stacked layer with a light source, where the driving layer is configured to change from the flat state to a curled state under an ultraviolet radiation environment; and the driving layer is configured to change from the curled state to the flat state under an ultraviolet radiation-free environment.

A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.

The embodiments of the present disclosure provides a glass panel of a display screen, of which each side bulges outwards gradually with respect to a connection line of opposing ends of the side, with a vertical distance from a point on the side between an end and a midpoint of the side to the connection line of the opposing ends of the side increasing gradually in a direction from the end to the midpoint.
