The invention provides a transparent LCD. By providing stop walls (4) in LC layer (2) to divide the LC layer (2) into the first areas (21) disposed correspondingly to the active areas (11) and the second areas (22) disposed correspondingly to the non-active areas (12), and providing LC only in the first areas (21) but not in the second areas (22), and by dividing the metal grid polarizers into polarizing areas corresponding to active areas (11) and non-polarizing areas corresponding to non-active areas (12), the polarization effect only occurs on the active areas (11) instead of the non-active areas (12), the invention reduces the number of TFTs, improves the transmittance ratio of the transparent LCD and simplifies the control system for transparent LCD.
