Patent number: 7929090Abstract: The invention relates to a liquid crystal display used as a display unit of an electronic apparatus and a method of manufacturing the same and provides a liquid crystal display which can achieve high display quality and a method of manufacturing the same. A liquid crystal including a polymeric component and having a specific resistance of 1×1013 ?·cm or more at room temperature (25° C.) is dispensed onto a TFT substrate.
