The present invention provides a liquid crystal display device which can obviate cutting off of a peripheral region of the liquid crystal display device which is provided with an inspection circuit and can surely perform the inspection of an image display even when the peripheral region is narrowed. The inner focusing zoom lens barrel includes a fixed barrel; a focusing cam barrel, a linear shuttle barrel, and a first cam barrel laid one over another in this order inside the fixed barrel; and a zoom linkage ring, a second cam barrel, and a 1st-lens-group sliding barrel laid one over another in this order outside the fixed barrel. The objective measure has a high correlation with mean opinion score such that a relationship can be formed between the objective measure and corresponding mean opinion score. A second buyer may use the second device to select a second item to order from the selected merchant. A specimen retrieval bag is coupled to the end effector and is deployed therefrom upon movement of the end effector from the first position to the second position.
