Abstract: PROBLEM TO BE SOLVED: To make it unnecessary for a user to switch on or off the backlight or front light of a liquid crystal display in accordance with the brightness level of outside light in a place in which the liquid crystal display is used and to prevent the consumption of a battery due to unnecessary lighting. SOLUTION: A liquid crystal display with a translucent liquid crystal panel 100 or a reflective liquid crystal panel and a backlight 200 or a front light is provided with a light sensor device 300 which detects the brightness of outside light in an environment in which the liquid crystal display is used and controls the switching of the backlight 200 or the front light on the basis of the detected result.

Abstract: PROBLEM TO BE SOLVED: To simplify a manufacturing stage and to obtain a bright and high quality display in a semitransmitting type liquid crystal display device. SOLUTION: In the semitransmitting type liquid crystal display device having a transparent area T in which a transparent electrode 4 is provided as a pixel electrode and a reflective area R in which a reflection electrode 5' is provided as a pixel electrode in a liquid crystal panel, the transparent electrode 4 in the transparent area T is formed by using an ITO film 4x and the reflection electrode 5' in the reflective area is formed by using a Ag film 18 formed directly on the ITO film 4x. And the transparent electrode 4 in the transparent area T is provided directly on a transparent substrate 2. Or, a gap between the reflection electrodes 5' adjacent to each other is shielded by a gate line 6 and a signal line 13 or light shielding layers 6x and 13x which are formed simultaneously with the formation of the gate line 6 or the signal line 13 by using the same material that used in the gate line 6 or the signal line 13.
