Abstract:
1. A liquid crystal display apparatus comprising: a liquid crystal panel: a circuit board including a mounting surface and a plurality of circuit elements that are mounted on the mounting surface to constitute a drive circuit for driving the liquid crystal display apparatus; and a case for holding the liquid crystal panel and the circuit board, the circuit board being positioned approximately in a vertical direction during normal use of the liquid crystal display apparatus, the circuit elements including (a) a plurality of first elements, each first element having a first projecting length from the mounting surface, the first projecting length being greater than a projecting length of any other element of the circuit elements, and (b) a plurality of second elements, each second element having a second projecting length from the mounting surface, the second projecting length being smaller than the first projecting length, the case having a first vent hole on its top wall and a second vent hole on its bottom wall, the top and bottom walls being located opposite each other in the vertical direction, the first elements being arranged on the mounting surface in a first column extending in the vertical direction from the top to the bottom of the case, the second elements being arranged on the mounting surface in a second column extending in the vertical direction from the top to the bottom of the case, the first column and the second column being located adjacent to each other to define a passage therebetween, and the first and second vent holes being configured to introduce air into the passage from outside the case, wherein each of the first and second elements is a capacitor, wherein the circuit elements further include a third element located in the passage, and wherein the third element has a third projection length smaller than each of the first and second projection lengths, the third element further having a maximum operating temperature lower than that of each of the first and second elements, and the third element is a central processing unit (CPU); wherein additional second elements are arranged on the mounting surface in the first column, and additional first elements are arranged on the mounting surface in the second column, so that the first column includes first and second elements and the second column includes first and second elements.
