A liquid crystal display device with both functions of transmission-mode display and reflection-mode display is disclosed, which device is capable of improving the display quality in each display mode to thereby obtain on-screen display images of high quality in either one of the display modes. In one exemplary implementation of the invention, a surge suppressor includes a plurality of flexible longitudinal members, each of which is joined to the other longitudinal members at a first junction and at a second junction spaced from the first junction along a central axis. The processing unit has a single connector for implementing the serial bus, and peripherals each have two connectors for propagating the serial bus.
