Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-contrast display panel that effectively incorporates a Si single-crystal substrate with a diffuser circuit for video signals and a TPT substrate for image display.

Conventionally, when displaying with a high-contrast TN liquid crystal, the liquid crystal and pixel electrode were sandwiched between two polarizing plates, and the structure was limited to placing a reflector under the lower polarizing plate, so the pixel electrode cover was required. is required to be transparent. Due to imperfect crystallinity, the TPT substrate cannot accommodate all high-speed transistors (1+ft 1/-0). On the other hand, with Si single crystal, it is possible to incorporate a high-speed shift register, but since it is opaque, it is difficult to integrate high-speed transistors. (The 4-light plate could not be placed under the pixel electrode, so the TN
LCD cannot be used. For this reason, only low-contrast, for example, guest-host liquid crystal display could be used.

The present invention eliminates both of these drawbacks and provides a compact display panel with high contrast.

The present invention will be explained below with reference to examples.
