A resin two-panel intergral-type holder holds first and second display panels of different sizes on two surfaces. The holder has a first bank-like rib which surrounds at least three sides of a periphery of the first display panel and defines first accommodating region and a second bank-like rib which surrounds at least three sides of a periphery of the second display panel and defines a second accommodating region. A conductive sheet member is formed on a first portion of another surface corresponding to the first accommodating region except for the second accommodating region and a second portion of another surface corresponding to the second accommodating region respectively. The conductive sheet member contacts another surface. A notch is formed in the second bank-like rib to electrically connect the first and second portions of the conductive sheet member.
