1. A liquid crystal display apparatus, comprising:
a liquid crystal panel that comprises an effective screen region, wherein
the effective screen region corresponds to a first front face of the liquid crystal panel, and
the effective screen region is configured to receive incident light;
a panel housing configured to accommodate the liquid crystal panel;
a first transparent member on a side of the first front face of the liquid crystal panel;
a frame member configured to hold the first transparent member, wherein
the frame member is attachable to the panel housing,
the frame member is in between the liquid crystal panel and the first transparent member,
a void is in between the liquid crystal panel and the first transparent member,
the void allows a coolant to flow along the first front face of the liquid crystal panel,
the panel housing includes;
an entrance flow path of the coolant at a first part of the panel housing, and
an exit flow path of the coolant at a second part of the panel housing,
the frame member includes:
an introduction hole that has a first end coupled to the entrance flow path, and
a discharge hole that has a second end coupled to the exit flow path,
the entrance flow path is in communication with the void via the introduction hole, and
