Description of the Invention: [Technical Field] The present invention relates to a transparent composite sheet comprising a cured resin of a transparent resin and a glass cloth embedded in the cured product of the transparent resin, and more specifically, A transparent composite sheet with less distortion of the fluoroscopic image. [Prior Art] A glass substrate is widely used for a liquid crystal display device, a substrate for a display element such as an organic EL (electroluminescence) display device, and a substrate for a solar cell. However, the glass substrate has a problem that it is easily broken, has low flexibility, and cannot be lightened. Therefore, in recent years, it has been continuously studied to use a plastic substrate instead of a glass substrate. However, the thermal expansion coefficient of the prior plastic substrate is about 1 to 2 times larger than that of the glass. When a display element or a solar cell is manufactured using a plastic substrate having a large thermal expansion coefficient, it is present in a heating and cooling process for forming a semiconductor layer or a color filter layer, etc. 'Because of a plastic substrate and a semiconductor inorganic film or a conductive inorganic film The difference in thermal expansion coefficient causes a problem that the inorganic film is cracked. In addition, when a display element is manufactured using a plastic substrate having a large thermal expansion coefficient, there is a large variation in the size of the plastic substrate due to temperature unevenness in the manufacturing step. It is difficult to perform mask alignment in the photolithography process (mask alig) Nment) problem. In order to reduce the coefficient of thermal expansion, for example, Patent Document 1 listed below discloses a plastic substrate obtained by applying a resin composition, impregnating it into a glass cloth, and then drying it.

Further, it has been found that in the vicinity of the glass fiber, the refractive index of the cured product of the transparent resin has a distribution, and the transmission of the transmitted light due to the change in the refractive index of the cured product of the transparent resin causes distortion of the above-mentioned fluoroscopic image.
