A process condition evaluation method for a liquid crystal display module (LCM) includes: a first step of obtaining a threshold power measuring pattern, an analysis sample for a cell bonding status in an LCD fabrication process, and obtaining a lower substrate sample by separating an upper substrate from the threshold power measuring pattern; a second step of supplying voltages on a gate pad on the lower substrate sample with sequentially increasing a voltage level by a predetermined unit by using an electrical device, and obtaining a threshold current and a threshold voltage by measuring currents at a drain pad whenever voltage increased by a predetermined unit is applied to the gate pad; and a third step of obtaining threshold power based on the threshold current and the threshold voltage, and thereby evaluating process conditions of the LCM.
