An electronic writing apparatus is provided. The electronic writing apparatus includes a cholesteric liquid crystal writing tablet, a trace recording unit, a processing module and a transmission interface. The cholesteric liquid crystal writing tablet has a writing/display surface for receiving a writing pressure to display writing trace according to a motion path of the writing pressure. The trace recording unit is disposed on a side of the cholesteric liquid crystal writing tablet opposite to the writing/display surface for detecting a position coordinate of the writing pressure. The processing module is electrically connected to the trace recording unit, and the processing module receives and converts the position coordinate to a writing data corresponding to the writing trace. The transmission interface is electrically connected to the processing module, and the writing data is transmitted to and stored in a cloud computing system or an external electronic apparatus through the transmission interface.
