Provided are thermoplastic polymer particles having an aspect ratio of 1.00 or more and less than 1.05, and a roundness of 0.95 to 1.00. The thermoplastic polymer particles are formed from a thermoplastic polymer resin in a continuous matrix phase. The thermoplastic polymer particles show a peak cold crystallization temperature (T) at a temperature between a glass transition temperature (T) and the melting point (T) in a differential scanning calorimetry (DSC) curve which is derived from temperature rise analysis at 10&#xb0; C./min by differential scanning calorimetry.

There is provided a method of driving a cholesteric liquid crystal display (LCD) panel by sequentially applying a selection line voltage to individual scan electrode lines and simultaneously applying data signals to all data electrode lines in order to select a state of each cholesteric liquid crystal cell according to a given gray scale level. Each selection time, during which the selection line voltage is applied to a certain scan electrode line and simultaneously the data signals are applied to all of the data electrode lines, is constant. Each selection time is divided into a first part time and a second part time. A low selection line voltage is applied to a relevant scan electrode line during the first part time. A high selection line voltage having a level different from that of the low selection line voltage is applied to the relevant scan electrode line during the second part time. A data pulse having a width corresponding to either the first part time or the second part time is applied to all of the data electrode lines at different time points according to the gray scale level of a relevant cholesteric liquid crystal cell during the selection time.
