摘要:
A speed doubling circuit receiving display data in one frame period and outputting field A display data and field B display data in one frame period. A field conversion circuit converts the field A display data to have a highest gray-scale if the display data has a high gray-scale, and converts the field B display data to have a lowest gray-scale if the display data has a low gray-scale. Between the speed doubling circuit and field conversion circuit, an emphasis circuit is disposed which emphasizes each of the field A display data and field B display data in accordance with the display data one frame period before and the display data in the present frame period.
摘要:
A backlight unit has a light source area. The width of the light source area in a first direction is shorter than the width of a liquid crystal panel in the first direction. A plurality of LED modules (31) are arranged along the second direction perpendicular to the first direction. End lenses (41A, 41B) and a middle lens (42) for enlarging a light divergence angle are disposed on the plurality of LED modules (31). The direction in which the end lens (41A, 41B) enlarges the light divergence angle differs from that in which the middle lens (42) enlarges the divergence angle. This structure can reduce difference in brightness of the liquid crystal panel, while reducing the number of light sources.

A gate line (40) has a two-layered structure comprising a lower gate line (40a) made of material identical to a pixel electrode (70), and positioned in the same layer as the pixel electrode (70), and an upper gate line (40b) layered on the lower gate line (40b), and made of material having a higher electrical conductivity than the transparent conductive material. According to this structure, it is possible to reduce the number of times performing exposure processes in manufacturing an in-plane switching type liquid crystal panel.
