Display device and display panel device

摘要

A functional sheet (3) is brought into intimate contact with a front surface of a plasma display panel (2), and the functional sheet (3) has a structure in which heat diffusion is superior to heat insulation between the plasma display panel and outside air. In addition, a display device includes a controller for controlling a drive voltage pulse train so that power consumption in a unit area in a light emission region within the screen is limited under a set value when one image is displayed.
