Liquid crystal display device capable of displaying large and small characters simultaneously

A liquid crystal display device capable of display large and small characters simultaneously, comprising:

• a plurality of liquid crystal tubes that are in the form of the digit “8” and that are respectively connected to corresponding segment circuits and common circuits, according to a calculation result, a control chip (CPU) being controlled to connect electrically the corresponding segment circuits and common circuits at corresponding positions so as to activate the corresponding liquid crystal tubes to thereby achieve the liquid crystal display device for showing digits;
• wherein:
• upper portions or lower portions of all the longitudinal liquid crystal tubes or those at specific positions are divided in the center transversely, and a transverse liquid crystal tube is disposed between the left and right longitudinal liquid crystal tubes and is connected electrically to the corresponding segment circuits and common circuits, whereby by activation or according to the calculation result of the control chip (CPU), the upper portions or lower portions of the liquid crystal tubes that are provided with the transverse liquid crystal tubes and that are at the specific positions or that are after the decimal point are controlled to display small characters, whereas the liquid crystal tubes that are at the other positions are controlled to display large characters.
