A liquid crystal display (LCD) cell for an LCD device is disclosed that can be manufactured under easy rework processing for reduced cost. The LCD cell comprises a first transparent substrate; a second transparent substrate; and a sealing member. The sealing member is sandwiched between and fixedly binds the first and second transparent substrates in a structural alignment for image displaying operation of the LCD cell. The sealing member forms a perimeter encircling a display area of the LCD cell and having a discharge port at a location on the perimeter thereof. The perimeter encloses an optimized amount of liquid crystal obtained after the excessive liquid crystal trapped within the perimeter during the manufacture of the LCD cell is discharged out of the LCD cell through the discharge port. The perimeter sealedly encloses the optimized amount of liquid crystal therein after the discharge port is plugged for defect-free implementation of the image displaying operation.
