摘要:
A thermal head of the invention has heating resistors each formed between opposite electrodes of a plurality of pairs of opposite electrodes on an insulating substrate. Each of the heating resistors is formed of a plurality of rectangular parallelepiped resistive elements which are electrically connected in series and supplied with different applied energy per unit surface area at the time of flowing a unit current in the heating resistor. These resistive elements are so arranged as to be the more distant from the resistive element of which the applied energy per unit surface area at the time of flowing a unit current in the heating resistor is the maximum, the less the applied energy per unit surface area at the time of flowing a unit current in the heating resistor.

A liquid crystal display device has a thin structure with a backlight device appropriate for illuminating a liquid crystal panel where there is no area in band form where the brightness is inconsistent. The size of the diffusion plate that forms the optical sheet of the backlight device is made smaller than the opening for illumination in the diffusion region, and the diffusion plate is not provided in the vicinity of the end portions of the opening for illumination in the configuration. In this configuration, the reflection properties are different in the vicinity of the end portions and as the center portion of the opening for illumination, and the brightness increases in the vicinity of the end portions of the backlight device, so that an area in band form where the brightness is inconsistent can be prevented from being created in the end portions of the display device.

An object is to provide a liquid crystal display device having a thin structure with a backlight device appropriate for illuminating a liquid crystal panel where there is no area in band form where the brightness is inconsistent.The size of the diffusion plate 103b that forms the optical sheet 134 of the backlight device 103 is made smaller than the opening for illumination Do in the diffusion region D, and the diffusion plate 103b is not provided in the vicinity of the end portions of the opening for illumination Do in the configuration. In this configuration, the reflection properties are different between in the vicinity of the end portions and the center portion of the opening for illumination Do, and the brightness increases in the vicinity of the end portions of the backlight device 103, so that an area in band form where the brightness is inconsistent can be prevented from being created in the end portions of the liquid crystal display device.
摘要:
An illumination device has at least one fluorescent tube, a lower frame supporting the fluorescent tube, a light diffusion plate which opposes the lower frame with the fluorescent tube being interposed therebetween for forward diffusion of output light of the fluorescent tube, a reflection sheet disposed along the fluorescent tube side of the lower frame for reflecting the fluorescent light toward the light diffuser plate, and an upside reflector covering an electrode of the fluorescent tube for reflecting the light toward the light diffuser. When letting a direction along a length of the fluorescent tube be a horizontal direction, a distance between the fluorescent tube and the reflection sheet at at least one of nearby portions of right and left ends of the illuminator is greater than such distance at a central portion thereof. A liquid crystal display (LCD) apparatus using the illuminator is also disclosed.
