Embodiment Construction

[0026] The present invention will be further described in detail below.

[0027]The curable resin of the present invention has a molecular structure composed of a dense structural part (A) and a loose structural part (B) as represented by the above general formula (1), and has at least one unsaturated bond. Here, the compact structural part (A) is a structural part composed of metal oxide parts with a packing coefficient Kp of 0.68 to 0.8, while the loose structural part (B) is an organic part or an organic part with a packing coefficient Kp of less than 0.68. Structural sites formed with organometallic oxide sites.

[0028] The compact structural part (A) is preferably a metal oxide part of the three-dimensional polyhedral structural skeleton in the structural unit represented by the above-mentioned general formula (I). In the general formula (I), at least one R should be an organic group having an unsaturated group represented by the above (a) to (c). In addition, it is no...

Abstract

The invention provides a display device which comes into being through taking advantage of a hard transparent substrate, which has the characteristics of the inorganic glass and the plastics and is good in curve resistance, and laminating various electronic materials used by the display devices. The hard transparent substrate can be obtained through hardening an indurative resin indicated by a general formula (1). The indurative resin has a compact structure part (A) which has a Kp calculated according to a formula (2) ranging from 0.68 to 0.8 and a loose structure part (B) which has a Kp less than 0.68, wherein, the weight ratio of the structure parts (A) / (B) ranges from 0.01 to 5.00. The indurative resin also has a least one unsaturated link, with an average molecular weight ranging from 800 to 60,000. -{(A)-(B)m}n- (1) (m and n are integers greater than 1) Kp=An.Vw.p / Mw (2) (An= Avogadro constant, Vw= van der waals volume, p=density, Mw=molecular weight, Vw=summation of Va, Va=4pi / R3-summation of1 / 3pihi2(3Ra-hi), hi= Ra- (Ra2+di2-Ri2) / 2di, Ra= atomic radius, Ri=radius of bonded atom, and di= interatomic spacing).

Description

technical field [0001] The present invention relates to a display device in which electronic materials for display devices are laminated by using a novel hard transparent substrate instead of a conventional glass substrate, and relates to applications such as computers, audio-visual equipment, mobile phones, information and communication equipment, games or simulation equipment. Display devices used in various fields such as navigation systems mounted on cars. technical background [0002] With the rapid advancement of electronic technology, especially liquid crystal display devices, touch panels, and optoelectronic fields are expanding. In general, photovoltaic elements provide various applications by forming the elements on a glass substrate with a transparent conductive layer. However, the glass substrate is heavy, and when combined with a mobile device, there is a problem that the weight of the device increases due to the high specificity of the glass substrate. Theref...
