The present invention provides a display panel and a 3D display device. The compounds of formula I are muscarinic receptor antagonists. Data from each transmit channel is buffered and converted to the frequency domain. In addition, in comparison with an image display apparatus that emits invisible light detects a position of a pointing element corresponding to a photoreception timing of the invisible light reflected by the pointing element, a complex detection circuit having a high time-resolution becomes unnecessary, and it enables to simplify the configuration and to reduce manufacturing cost. The storage container incorporates interconnected components which facilitate changing the storage container between a non-collapsed configuration and collapsed configuration.
